How much room is inside the Nexus 7? - Nexus 7 Q&A, Help & Troubleshooting

As the title asks.. How much space would you say is actually inside the nexus 7? Is everything super tight in there?
Reason I ask is that I have an idea. I am wondering if there is enough room to stuff the internals of a really thin SD Card reader in there. If yes,
then the next question is there room to access the wires going to the micro USB port? The plan would be to solder in the wires from a OTG cable and run it to the Card reader.
So basically I am wondering if it's possible to wire in a card reader, run it as OTG and have a Nexus 7 with expandable storage..?
P.S. I don't have a nexus 7 and I ask because if this is possible I might as well buy the $199 8gb version and use the money saved to buy the parts needed to make this work. (if it's even possible)

Even if you could fit it in and wire it up, how you gonna write to it? If it's "hooked up" via the OTG cable you spliced into the existing cable to the Micro-USB port, it's a fair bet that the device will not "also" be able to connect USB to the PC at the same time. And this is assuming it were even possible to begin with for the device to write to an external SD Card via OTG directly. I know that the Flash or SD card can be pre-loaded with media PRIOR to being connected to the Nexus, but I I don't know if A: The Nexus can write directly to said card or B: it could so so while also connected to Windows. The first one someone who has an OTG cable can check easily enough. But that last one is impossible to check on a device that isn't already modded. Also remember that as far as Android is concerned, you already have an SD card. It's just virtual. Not sure how it would handle having two. Honestly I doubt this would work but you could always try.

As I recall - the Memo 370T did have an SD card reader.
From the IFixit teardown, the motherboard in the Nexus 7 is from the Memo 370T.
There is definitely a spot for the (removed) back facing camera, and as I recall
the SD pads are available. Of course, that might have been for HDMI, since the presenter units had an HDMI connector.
Have fun tearing your Nexus 7 apart - nothing is worth the risk to me.
I like my Nexus 7 as it is...

I've used OTG on my Nexus S and what it does is mounts the USB stick or SDcard as and external drive. So basically, yea you will have to go into the USB OTG app and mount the SD card to start using it. I never played around with it enough to see exactly how it works so maybe somebody with experience can fill us in with that.
I see your point about plugging in the tablet into the computer. But I don't see why it couldn't at least charge the device even if you mounted the SD card. I could be wrong, I am no expert.
I thought that the OTG app actually enabled you to use the internal sd and external USB storage at the same time. Somebody please clarify. So if that's true, then browsing, play videos/games/etc should work as normal. It will just treat it as another drive.
I don't know how it would work if you plugged it into your USB port on your computer with OTG enabled and the SD card mounted but like I said, maybe somebody who specializes in this can clear this up.

usb thumb drive instead of PC?

I tried searching to see if this has already been discussed, but like all vBulletin forums, the search function rejected USB and Pen (as in pen drive) and a few other essential but three-letter words. So I found zero.
I have a 4 GB USB U3 thumb drive that I always carry with me--until I lose it, that is. I would like to load it up activesync (or not--whatever works) and a whole bunch of files I want to install on my HTC Touch Pro (AT&T Fuze). I have a short cable with a male mini USB connector at one end and a female regular-sized USB connector on the other (so I can slip the male USB thumb drive connector into the cable and thence connect it to my TouchPro).
I'm not sure whether this will work, but it seems like it should. This way, I can carry with me all of my files-to-be-installed and work on customizing my fuze anytime, anywhere. I don't want to store the installation files on my micro SD card because that wee thing holds soooo very little. (i have a 32 GB F card and a 32 GB SD card in my iP 211.)
For starters, I can't even figure out how to install Windows Mobile Device Center on the thumb drive--the process keeps wanting to mess with the AS/Winmobile Device Center already istalled (and used for another WM device).
Maybe there's a way to do with without AS or the Device Center. That's fine with me. All I care about is having access to the many, many apps I have waiting on the flash drive.
Any ideas?
Thanks,
Sandra
Im no expert, but I dont think many devices have the capability for being hosts, meaning they cant have external memory devices attach except through the supplied card slot.
There are a couple out there which can handle it, but they normally come with a usb port built in. Otherwise I doubt its possible. I dont think its one of those things which can be programmed. Of course, I could be entirely wrong about it.
Edit: Ok, im completely wrong about it. I just found a web page through google saying that many devices with wm on dating back to Pocket PC 2002 do in fact have the ability to do it.
My bad. lol

What size do you have? They are currently available up to 16 gig, and 32 is coming. I keep all my cabs on my Sandisk 16. As for USB host, see the post above with the link to the thread. The chipset does not appear to support it. BTW, if you do a search on "USB host", you will find the thread.
I'm about to follow those links you guys recommended, but I wanted to say a quick thanks to you all. I didn't know anything about USB hosting, etc, and it's a whole lot easier to think anything is possible if you don't know anything than if you are well-educated. (OTOH, I suppose that that knowing might also inhibit experimenting which means you don't pursue new ideas. Hence the box we have to think outside of.)
Thanks again,

I'd recommend a Trio adapter: Trio is not a brand name, just a mechanical name they have given this adapter. I had one made by A-Data and its awesome.
The adapter itself is an SD card that accepts a MicroSD on the side. However, the neat part is the fact that you can remove a piece and voila! you have a USB stick.
http://memoryworld.com/product_info.php?manufacturers_id=14&products_id=386 is the first hit from google. I bought mine from Newegg way back in the day. Sadly it was ran over when my phone was. The MicroSD card was good, but the adapter died. I am saving up to get the new SDHC version and a 16GB MicroSD card.
BE ADVISED: there are similar products out there called DUAL adapters: the memory is non removable in those. What that means is that there is no MicroSD card that comes out.
Enjoy!

Transfering SDHC Content to Touch HD

Guys,
I'm soon going on a trip to the Lake District (UK National Park) and will be doing a lot of climbing/hiking/walking.
Whilst I am at the summits of certain 'Fells' I will be taking photo's with my Digital Camera.
At that point I want to transfer Photo's from the Camera to the Phone and send them directly from the Phone.
Problems I need to overcome:-
The Camera uses SDHC.
The Phone uses MicroSD.
Apart from the Phone there is no power source.
What do you think is the best way to transfer the Photo's to the Phone so that I can then send them over 3G?
Thanks in advance.
Why not use a Micro sd in a Micro SD to SD adaptor, that way you are storing the camera images direct to a micro SD card and can then just put that in your phone to send the images

The camera will not take an adapter.
Don't forget I won't have the option of using a computer.
Why will the camera not take an adaptor I have used these adaptors ina PC and they work just the same as if you had put an ordinary SD card in.

Can you show me which adapter will connect directly to a camera WITHOUT the need for a PC.
Surely you need the PC to transfer the data across?
You can get SD adaptors that are just the same size as an ordinary SD card with a slot in the end to fit a Micro Sd card. This means that they fit anywhere a SD card fits and appear like a SD card to the device they are fitted to. A search on google for "sd adaptor" will find one.

Yes but that would mean taking the photo's DIRECTLY onto the MicroSD Card.
I use high speed burst mode with my camera and that requires a fast SDHC Class 6 16GB Card.
You can not get a 16GB Class 6 MicroSD.
Although some will be released very soon the difference in price is quite high.
I'm trying to overcome having to chop and change cards between camera & Phone.
I am seeking a lead or something on this vein for transferring the data across.
Surely you're going to have to make some kind of sacrafice at some stage, either:
- Shoot on Class 2 MicroSD (via SD Adapter)
- Take laptop/netbook along
- Only other viable option is some kind of device that replicates SD to MicroSD without a PC - I don't think it exists.
You sound like your probably using a DSLR, have you thought about the time it will take to tranfer each photo over 3G, even assuming you can get 3G reception in the Lake District browsing the net on mine can be frustrating enough never mind uploading 4Mb photo's.
Oh and the power issue is pretty big! Have you got a windup/solar charger or a shed load of spare batteries?
Good luck though - it's a worthy cause

Thanks for the feedback.
Yes, I'm shooting with a couple of cameras (Big Nikon D2Xs & a small semi-pro Panasonic LX3).
The Nikon though uses CFII for storage and I aim to use this camera with it's heavy zoom lens at the foot of the fells.
The LX3 will be going up with me to the top this time as I've done the Nikon before (and what a weight it was).
The last time I had all my gear... Laptop, Mobile 3G, Solar Charger, etc. etc.
This time however I'm trying something different and want to go as light as possible.
I've got the new Proporta portable charger and this will give my Phone plenty of charge.
The LX3 has two spare batteries so that's not going to be an issue.
I did think about using a mobile hard drive like the Archos AV700 (which I have).
It requires no power source using cable alone and has USB Host.
However, it would mean more weight and cables etc.
I just wondered if there were another simple way I could achieve my aim.
I intend to transfer around 3 to 6 pics and appreciate what you say on the speed issue (agree fully) but I want to complete the task which will help in the review I end up writing.
Hi Beards,
I tried but don't have all the right cables to prove it.
I thought the USB on the HD would also behave as a master for storage - so I thought I could connect a USB to a SD converter and that would be the solution. BUT, I don't have a USB female-female connector. I do have a micro USB to USB cable and a USB SD convertor. My aim was to plug it all in and try - Sorry.
Maybe this will work for you with the SD card appearing (hopefully) as storagecard2 but I need the extra cable to prove it.
Only other issue I can think of is the pictures will be big so no MMS transfer will be possible. Only email attachments and then I think there might also be a limit.
Have a great trip !

Hi Dave,
Nice speaking with you again.
Thanks for the heads up, this sounds promising.
I've got a couple of weeks to try and sort it out so if you come across anything suitable do please let me know.
Been far too busy in theatre lately. This trip will make a perfect break.
Why not just use the camera's 50mb internal memory to copy from your cheap high speed SDHC card to the micro SD card in SD adaptor combination already suggested? Since you're only talking abut 3 or 4 photos it shouldn't be a great hardship, and you get to shoot the way you like.

I'm not taking 3 to 4 shots shuflie.... I'll be 'transferring' 3 to 4 shots to the Phone.
I will be taking around three hundred odd shots in total. I've then got to pick which will then be transferred to the phone.
It's an interesting concept though....
The MicroSD to SD Adapter keeps cropping up in topic here. So on basis this needs to be investigated further.
Edit:
I have just checked the Manual on the LX3 and it would appear this procedure can be done.
According to the Manual I can copy data from an SDHC card to Internal Memory and vice-versa.
So.... all I would need to do is:-
1. Pick from which shots require transferring.
2. Transfer them into Internal Memory.
3. Take out the SDHC Card with all the photos on.
4. Insert the SD Adapter with MicroSD card.
5. Transfer the selected Internal Memory shots on to the MicroSD card.
6. Take out the Adapter and MicroSD card from the camera and remove the MicroSD from the SD Adapter.
7. Insert the MicroSD card into the Phone and temporarily place in internal memory.
8. Take out the MicroSD card and replace with the correct storage MicroSD card.
9. On the Phone, transfer the shots from Internal Memory to the Storage card.
10. Send the shots over 3G.
Phew........ but at least it should work.
DSLR image sending via Touch HD
Hi Beards
I am a news photographer and do exactly this all the time.
There are sacrifices that pretty much have to be made.. you can't do everything you want without power and a laptop / or loads of extra kit.
The sacrifice is basically you cant shoot on class 6 cards you are stuck with the speed of the microSD. However.. we shoot riots, news, entertainment, etc in RAW mode on a Canon DSLR and unless we hammer it and motordrive loads of shots we dont have any problem with the slow microSD cards from SanDisk. I'm not sure what you plan to burst shoot but i would suspect if it serves us ok doing breaking news it should serve you ok up in the countryside. (unless you are doing motorsports or something )
Our workflow is this..
We shoot RAW images on the Canon EOS1D mk II on a SanDiskc 8bg microSD card in a SanDisk SD card adaptor.
We put the microSD card into the touch HD and use an application called Phojo http://www.idruna.com to extract the jpeg image from the raw file and email or FTP the image from our phone. Phojo has a lot of pro features that you may or may not need.. although it is commercial software so may not be something you want to invest in.
Of course shooting JPEG should mean you can shoot even quicker as the files are less than half the size of the raw images and you dont need Phojo to do the extracting of files. You can of course use the touchHD's built in email software then to send them by email if you wish. We recomment Phojo however because it is specifically designed for this application.
There are obviously other solutions.. you can get battery powered tiny USB transfer devices (belkin used to make one) that will transfer the content of one usb device (card reader / card) to another. However we havent had much success with these and they are fiddly.
Your needs match very much what press photographers do every day. All the ones i know do it by using the microSD adaptor / Phojo method (altho most dont shoot RAW they shoot JPEG) The ones who dont use the microSD method are either using a wifi transmitter made by canon or nikon on their camera and Phojo or they are using a PDA/Phone that supports USB host or SD cards.
Hopefully this helps
kind regards
Edward
Equinox Features
http://www.newspics.com
Newspics, that's really interesting. Great to see how the pro's do it.
I feel like there sould be camera's with built in capabilities to upload pics by now. Or at least Bluetooth 3.0 between the phone and the camera. Live Mesh does a pretty good job for me for syncing pics to my PC, if only it could sync between Camera, Phone and PC.
If you will have no access to a power supply how are you going to keep your phone charged?

Sometimes, microSD is better than SD

I've seen many people complain that they wish the Iconia had a full-size SD slot and not a microSD one. Today, I realized that microSD can be a big advantage.
My wife is on a school trip this weekend, currently on a bus with 60 high-schoolers. She just called because she realized that she'd left behind some important instructions that she's supposed to read to the kids on the bus. I can e-mail them to her, but the problem is that the tablet (my Acer Iconia) doesn't have a WiFi connection on the bus and lacks 3G so she can't receive the e-mail there. The instructions would be too small to easily read from her phone. Fortunately, her phone is an Android one with a microSD card. So, I've e-mailed her the instructions - she can save them on the microSD card, swap the card into the tablet, copy the file to the tablet's memory, and then return the cards. This will put the document on the tablet, where she can easily read it.
This made me realize that a similar solution would be useful with photos. I can take the photos on my camera, copy them to the tablet and convert the RAW images to 800x600 JPGs. Next, I can put the JPGs on a microSD card in the tablet's card slot and then put that card into an Android phone to e-mail them as desired. True, having 3G on the tablet, or setting up tethering with the phone, would be better options, but neither are available to me at the present. So, this will be a great solution - when I replace my iPhone with an Android (I hope to have a Samsung Galaxy SII LTE/Skyrocket soon).
Thanks for that post. It just shows how far we have come with technology over the years and how tablets are becoming part of every day life.
Just be careful putting the SD card in and out of devices. I think the locking tab on most micro SD cards is much too small and will wear off. This will make the card not hold in.Safari as the Iconia its tough to get micro card locked in .for me anyway.I don't think micro slots should be mechanically spring loaded to small to work correctly.
You can do Bluetooth file sharing between tablet and iteration non android devices.just pare them. I think you have to send the file from the phone.
From my touch pro2 i send files to the A500 via bluetooth. Im sure you can do the same with a android phone. I wouldnt go swapping cards from device to device.
Why didn't she just connect her Android phone to the USB port of your iconia via the cable?

I've found that bluetooth usually works pretty well for transferring small files. It seems to be too slow to transfer larger files quickly, however. With files over 20mb in size I try to use a cable, or even a thumb drive with the acer.

Do the MicroSD cards have locking tabs? The ones I have dont.... thought it was only on the full size.
But aside from that... the OP had the exact same thought as me when I got my tab. Although i really wanted a full size SD slot for the extra capacity and to swap with my camera, I ended up using a Mini/Full SD adapter to use the Minis in my camera.
I bought this from my local Kmart and use the USB adapter in my A500 to read MicroSD from my phone or another tablet. Beats the crap out of actually trying to fiddle the one out from my tablet, and it has the bonus of being able to plug into my PC and my car stereo's USB port if I want to listen to music from it.

Works really well and its a tiny little thing, I can leave it plugged into my tablets USB port all the time and it doesn't get in the way too much at all.

Not write protect locking. Ian refering to the tiny bump on the side of the card that holds it into the slot.This is not used on many phones. But the Iconia SD card locked in by this tab.I have a SD card I used alot between two phones with music on it.this card will not stay in position on my tablet that lock (little bump on card) is worn off

Even with USB storage turned on it won't recognize it! My computer can see both drives on my phone just fine but the tablet gets nothing :/
I intentionally bought a micro SD card + SD adapter for my digital camera so I can easily swap the card into my tablet to transfer photos over. Yes, a USB adapter would have done the job with a regular SD but this is one less thing to carry around. Now I can swap Micro SDs between my tablet, camera and phone. It feels good to be connected

USB on the go questions

Hi just got my new nexus 7 and it's awesome but I got storage question.
I got the 32 gig and try to add some video s only to find that I quickly filled the damn thing. So I guess that I do need the USB otg, I have a 32 gig micro sd card and was thinking about buying a 64 gig card on cyber Monday.
So I have two questions:
Is there a difference in speeds between USB micro sd card readers?
Will the USB micro SD card reader limit the speed of the class 10 card?

hello mate, the speed is in the card not reader, use a class 10 card and that is all the speed you need otherwise the readers are pretty much all the same.
I am fairly sure the card reader itself has to support class10 (I suspect all modern ones do), and there is still the problem of the slowest part will still be the USB connection between card reader and the Nexus 7 - which is USB 2.0 (?) - although I'm not sure if class10 would saturate a USB 2 connection.
I would also try and get a mains powered one, not a USB powered one. I have 2 here and the USB powered one, with a wireless keyboard+mouse (Logitech MK520), + PS2 Joypad wired does cause a random reboot problem at times - possibly due to lack of USB power.
My mains powered hub is a cheap Xenta hub I got from Ebuyer and works a treat.

yeah I though about that but I will mostly be using this at the university and during rides and having an external hard drive kind of ruins the portability of a tablet and makes my laptop a better choice, but I want to play with my new toy!!!
I looked around the internet and from what I read is that usb 2.0 can go up to 37mb/s and even the SanDisk Ultra 64 GB MicroSDXC Class 10 UHS-1 Memory Card tops out at 30mb/s. however the microsd card reader can very in compatibility from just microsd to sdhc all the way up to sdxc so even though you dont need usb 3.0 for speed the only card readers Ive seen that support sdxc is the usb 3.0 ones (if you use any that don't know let me know. SDXC is the only format that can go above 32gigs
I think I'm going to go with Kingston MobileLite G3 Card reader i read this review legitreviews com/article/1977/1/ H
its pretty cheap and and I guess future proof.

My mains powered hub is a cheap Xenta hub I got from Ebuyer and works a treat.

How well do keyboards work on the Nexus? And do standard shortcuts like copy/paste work as their normal shortcut keys?

From my own testing, wired keyboards work best, just plug in and away you go. Wireless, I assume, will need Android to support the wireless adapter. I have the Logitech MK520, and the god-awful Microsoft Ergonomic 7000, and both worked fine with both the Keyboard and Mouse working well in Android 4.2. I also have a cheap USB mini keyboard I got from Amazon here,
http://www.amazon.co.uk/Leather-Keyboard-Compatible-Blackberry-PlayBook/dp/B008QBFFR8/ref=pd_ybh_2
Awkward because of the keyboard's cable + OTG cable sticking out, but it worked surprisingly well.
Just for completeness, I also tested a Xbox 1 & 2 wired Joypad, a Xbox Arcade Joystick, and a PS2 Wired Dualshock2, all worked well, especially in emulators that had hardware joystick options.
In the week I intend testing a couple of wireless adapters to try and better my internet connection from sat in bed - The router is located at the far side of the house and only gives me 2 bars.
Hope that helps.
Edit - Bloody Capchas. How long does this go on for ?
Instead of editing my post I thought I would post this to hopefully help anyone who is thinking of getting a OTG cable + keyboard + USB Hub.
This may have been my device, Android 4.2, a combination of my hub + keyboard + non-rooted Nexus 7, who knows, but I can reproduce this fairly easy.
Lets take a similar situation to what happened to me. I popped the Nexus in the wallet, connected up the keyboard, took it round a mate's house and showed him a 7" tablet and how it works. We surfed the net using the keyboard for typing websites, searches, forum posting. etc... I then went home, device is switched off with everything still plugged in. I unplugged the keyboard, took the nexus out of the wallet/case and switched it on but it didn't come on and I honestly thought I had bricked the device, or the USB port overloaded or shorted. Googled the problem and it turned out a few had similar problems and the answer was to hold down the power switch for 10, 15, 20, 30 seconds until you see the Google logo, the Nexus will then boot up.
Now I can reproduce this just like the above. For example, sit in bed, type this reply out on the keyboard, switch off the device, go and make a coffee, come back and switch on the device with everything unplugged and the Nexus will not switch on. No idea why, but every time I have to hold down the power button for at least 15-20 seconds. If I just switch back on the Nexus with the keyboard still plugged in then it works fine.
Now, thanks to someone on this board, I have now done a few backups of my device including the SDCARD, so I might unlock it + root it then try it again with the Nexus wiped clean and see if it still doesn't come on.
Like I said, it could be some bizarre hardware + software combo, or just hardware including hub, but I thought I would post this incase someone here switches on their device and it too doesn't come on.

[Q] Hard Drives & MicroSD

1. What format does the drive need to be to be read by the MOJO?
At the time of this writing: Hard drives need to be NTSC. They are mounted as READ ONLY, so you will not be able to save files. Bummer.
2. Same question, except for a 64GB MicroSDXC format...?
At the time of this writing: microSD must be formatted as FAT32 with 32K cluster size. They need to be set as a PRIMARY drive rather than LOGICAL.
1. NTFS or FAT32 usb 2.0 HDs work. I've tried USB 3.0 HDs and so far those haven't worked
2. I havn't tested a 64gig micro sd but most Android devices only recognize up to 32GB sd cards.
I've got a 64GB in my A700 and it works fine as FAT32. The CM ROMS have issue with it, however. Also, according to the MadCatz website: "For those of you who need more, there’s a microSD flash slot to accommodate SDXC cards up to 128GB!"
What format is your MicroSD?

I'm using a 64gb micro sd, format FAT. Works great.
Try exFat. It's the "standard" format for SDXC type cards and unlike Fat32 you're not limited to files less than 4 gigs in size. It's the format i use on my Galaxy Note 10.1 (last year's model). It should come in exFat anyway.
Or the simplest solution would be to rip open the packaging, stick it in the MOJO and if it tells you it needs to be formatted format it. That way it's in whatever format the MOJO prefers and your pc/laptop in all likelihood will recognise the format.
Also I'm guessing you're just going to leave it in there most of the time. To avoid card readers and sync cables I normally use FTPServer on my phone and tablet and the filezilla client on the pc, and to transfer stuff to the network drive I use the android ftp client andftp (there are file explorers like ES Explorer which can handle samba connections and FTP connections but I find they're a bit slower).
Avoid NTFS on flash media. From what I've been told it uses too many read/writes which isbad for flash media due to their limited write cycles.
Yeah, I didn't even think about formatting until after I had loaded my card down with movies and music and games....exFat = Nope.

FAT32.
Time to backup and reformat.

No ExFat support? Wow. Mad Catz put NO effort into the software of this device, did they. Just using the stock OS without bothering to add in bluetooth 4.0 support and just throwing in a dongle to compensate (various phone providers, i.e. HTC have a history of providing a better than stock bluetooth stack), no camera support, no exFat support (this just makes them cheapskates since they just needed to license it crom Microsoft like the phone makers that provide it on their phones and tablets).
I still have time to decide. I was planning on buying it on amazon, sending it to a friend and then having them bring it when they visited in order to avoid the overpriced shipping and import fees but I'm starting to think I'd be better off with a cheap quadcore A15 device with an SoC like the A80 from allwinner and a Moga controller. It would be cheaper, have better play store support and be more versatile from what I'm reading on here...
Considering how little effort they've put into the software I wouldn't be surprised if they never got around to the KitKat upgrade. Companies who put more effort into the OS often fail whdn it comes to promised upgrades. And if Mad Catz never upgrades the OS it means users are limited to just ONE USB port which seriously cuts dow on usability.
Wait, are you saying you can only use one usb port at a time because of the OS version?

yes beacause if there's no update to kitkat the BT smart dongle is in one already and will have to stay there.
I think it will come out, they have said it would a few times now. so just a matter of when.
yip I tested mine, no exFat support... a bit of a shame
Buy an USB Hub.
You can use hdd with ntfs should be much better then exfat.

At this time- the controller requires a dongle which takes up one of the usb slots.
You are left with the micro SD slot and the usb 3.0 slot.
When the Kitkat update arrives, you will be able to remove the dongle and have the usb 2.0 slot available.
The usb's will probably be obsolete soon anyway- seeing as PC streaming is coming in the kitkat update.
The point of mojo is to do everything via bluetooth and wifi.
That's the beauty of the machine.

Why use a usb to transfer data when you can pull data/stream data from your pc?

First of all, the point is that you're not getting the functionality promised. You are told that it's a micro-console with TWO usb ports and you can either give up the controller, or give up a usb port. Secondly a usb hub can be an okay solution but you then have to worry about getting a normal one or a powered one and how much it will affect throughput splitting it up depending on what devices you have attached. And as is others here have reported problems in using both USB drives simultaneously (and that some drives work better in one than the other).
Yes, streaming is good, you can actually use it right now if you´re just talking about transferring files, but if you're told you'll get two USB ports you should GET two functional and available usb ports.
KitKat upgrade. They've mentioned it, but don't think there's actually an official announcement. Plus they could have had that functionality there since the beginning. Smartphone and tablet makers add/take away functionality from Android and its Kernel. Heck, people HERE do it all the time. So why can't Mad Catz. And how long exactly do people have to wait for the upgrade? As the saying goes, buy a device for what it can do today, not what it can do tomorrow. Manufacturers often don't come through on promised upgrades.
Also to say that you/they support SDXC without a disclaimer saying that you can't use exFat is fraudulent as exFat is STANDARD on SDXC. If they made all this clear from the beginning it wouldn't be so bad but they don't and as such mislead their (potential) clients. Who cares about friendly and speedy support if they can't actually solve the issues present?
I would use the USB to hold a thumb drive full of data like the ISOs I've ripped from my GameCube and PSX for emulation. (Trying to get my wife to give up the Wii to our son when the Android port of Dolphin reaches maturity).
Formatted my card as FAT32, loaded it down, NO LUCK.
Tried the card in two computers and it shows up as FAT32 with all files intact. I'm on my A700 right now, popped it in, and it is working just fine.
There really needs to be a reboot option on the MOJO...Yes, I rebooted..no luck. Causes FC from settings when I try to see my storage.
Thoughts?

When you put the USB in, do you see it say, preparing USB in the top left?
You then have to go to your mojo settings, storage, and 'mount USB'.
It will. Then show up.
To unmount, go to settings, storage, unmount.
Working now?

Nothing.
When it was formatted as exFAT, I could at least get to the storage options...just wouldn't mount.
I'm trying an extHD to connect.
First try 1 partition 1TB NTFS - recognized and mounted without problems on USB 3.0 port. (but NTFS don't work on my LG G2)
2nd try 4 partitions 1,2,3,4, extFat 256GB recognized, but can't mount. (but works fine on LG G2)
3rd try 4 partitions 1 NTFS, 2,3 extFat and 4 NTFS - don't work
4rd try 1 partition 1TB extFat - can't mount.
So, I let this thing NTFS formatted now. :silly:
If the M.O.J.O could be rooted, we could use tools to mount ALL formats and ALL partitions.
Solution for my rooted LG G2 was simple. " Paragon NTFS & HFS+ " is a free tool in Play Store.
NTFS is r/w now on my smartphone and r/o on the Mojo.
