Has anyone tried plugging in a USB HDD?

i was wondering, what if i got a USB harddrive, and plugged it into my hermes?
would WM6 even notice its there?
this is assuming i've got a externally powered HDD that uses the normal USBHOST.
i searched "usb harddrive" in the hermes forums and not many things turned up..

If you have one lying around, give it a go?!

that might be the clue to your answer..... the usb port in the phone lacks the capability to host an actual usb device, whether the external device is powered or not... But give it a go anyway... i cant think of any harm in trying... unless there is some kind of major power backflow, but that shouldnt happen unless your external device is faulty

the OS may support it, but hardware-wise - i dont think the Hermes supports USB hosting? or does it?

My brain says no...
But the hope in me says yes...

Wondered about this myself before.
Doesnt the HTC have the ability to act as an external UsB drive through the USB port when connected to a PC using the Advanced USB settings. Maybe its just a question of reversing the settings maybe with an added utility or something i have an external hard drive but not converter to convert the full usb to a mini usb

having the device mimmick and external drive and plugging in external storage through USB are 2 completly different things... and it all comes down to the USB host... when you plug your phone into your pc your computer then is able to act as a usb host, as it has the power and the drivers necessary for that... the phone itself lacks the abiltiy to be able to become a usb host...
but hey, at least your thinking

So it may be possible to access a USB HDD if we catered for it using a driver of some sort (written by us guys ofcourse). This may even show up in the file manager as something like /Hard_Drive.?

main procesor (and also OS itself) have support for USB host, but for some reason HTS decide to not enable this feature, it was asked many times, but solution doesnt exist yet... I used this functionallity on my old Fujitsu-Siemens LOOX n500 without necesity to install any drivers, or registry hack, after connection device had available after few second. It was WM5 device.

well think about this:
keep a laptop usb HDD in your car, 160GB of music at your command, with TCPMP who needs a ipod?
i've already modded my stock headset cable to have a 1/8" miniplug AND RCA's on it, so i'm set for the output, but my 4GB of microsd cards just don't cut it
so i'm working on tryin' to find a usb mini b male to usb b male cable right now, might just have to solder one up myself-- i'll post to see how it goes.

I think I've seen them for sale at Radioshack and Compusa - might try peaking in there though if you have a bunch of USB cables kicking around probably cheaper to solder

IF you look around on the net somewhere, someone successfully made a wifi hard drive, and i think it was fairly inexpensive... He loaded tons of mp3's and would access them from his phone via wifi.

Looks nice!

I just tried this. And nothing happens. Tried a usb memory key (low power), an external HDD (on its own power supply) and a card reader, none of them did anything.

thanks for the go.. after my weekend spent messing with *nix and tryin' to get into locked up wifi, i was spent.

[Q] MicroUSB to ethernet ?

I've an HTC Desire HD and can connect via wifi, I could connect via cable and tether a PC via the phones 3G signal etc However, I was wondering if, in the absence of USB connectivity and no wifi or 3G, would a USB to RJ45 cable be made to work? That is, having a wired ethernet connection to the phone's microUSB port. Obviously you would need an ethernet driver on the phone.
Now I don't have an immediate need for this, it's more a case of 'I wonder ...... '. I've read that USB host mode is not possible but not sure how/if that would negate being able to driver ethernet over the microUSB port. Anyone know for sure?

I think the answer is not without usb host, and the cable would need to be more like a dongle with a nic in it.

I have seen this work using a Router with a usb port.
It requires a Linux router with enough guts to do it, Tommato/DD-WRT running, and one must fiddle with it. Essentially one uses the router to share the internet USB connection. It is probably the cheapest and most supported route.

That would be lovely though .. Ill try it later ...

Let us know how it goes.

Back in the day I had an HP iPaq that didn't have WiFi built in, but I could connect it to a wired network via a small adapter that functioned as a nic. Hypothetically you could find or fashion such a device to function over mini-USB, and then write some drivers to get it to share data with an attached computer. Just my 2c.

If you want to write drivers, you have a whole new level of complexity.
USB port of a router is a known cheap solution.

I'd have to second the OP's idea, as it does have merit. Hopefully the work on getting the USB Host working can show some results in the future....
However, I'm in the same boat, where I have a Nook Color running CM7 I use as a tablet, and an N1. I'm also on business in China a lot, and I prefer to use the NC in place of a laptop, although in some places wireless is flakey or non-existent. In those scenarios I'd rather not use the N1 as an access point using the 3G network to run data, as it adds up quick, even when using China sim cards.
It's these situations where a means to connect an android device to a physical ethernet is desirable, whether by USB or by wireless to a dongle.
This is the one device I'm testing out now is a CQR-980 from Cnet. You'll have to google it, because I can't post links.
The reason for this unit is it's size (its 3.52 (L) x 2.32 (W) x 1.06 (H) inches), and full support for setting up a secure wireless environment. If it works right, I will pre-configure it as an access point with WPA2, and it should be able to be plugged into any ethernet port in a hotel or otherwise, and I should get an IP on the NC or N1 via wireless.
If anyone else has found a better way to make this sort of setup work, would love to hear of it. The fewer devices I have to bring the better. Yet this is still better than dragging even a small laptop around.

I have seen this work using a Router with a usb port.

The Phone got to have specialized hardware to enable it to use just that USB to RJ-45 cable.
But in my experience, I could be wrong about it. Don't know what the R & D guys will cook up next.

This could make the job of having RJ45 connected to USB?
http://www.cnetusa.com/eng/CQR-981.php

Also this seems interesting:
http://www.euogo.com/usb-lan-adapte...to-rj45-adapter-for-android-tablets_p420.html
Will it work with an ASUS Transformer (Honeycomb 3.0)?

I have looked around a lot on the web for the MicroUSB to RJ45 Ethernet on a Droid, no luck. I have small hardware devices that have embedded configuration servers that are only accessible via TCP/IP Ethernet RJ45 ports and I normally use my netbook for that. I thought it would sure be cool to be able to access those embedded servers via my Droid2G for example, and get rid of the netbook. It seems like the phone can do almost everything else.
I've read about USB host mode etc, and the mini dongles with NIC's in them seem more promising, but I guess there has not been a big enough need for the guru's to go after it. Aparently it may available on the Android 3.x tablets but no able to backport to Android 2.x? Verizon will likely never upgrade my D2G OS.

What if you used this but also used a usb extender so you could plug in the phone cable to the usb to rj45.? Then all that would be left would be the drivers.

With the exception of cybdroid's situation I think that a little wireless ap would work great. I have a little netgear wgr101 that works great.. you connect it to a rj45 port in the motel, and then wifi from the phone or laptop.
The reason i'm on this tipic, is I was thinking rj45 to rj45 on a copier. Then I can set same subnet, and ip range with a crossover cable(or ipx on on the copier). Then I wouldn't have to use a full laptop to troubleshoot...
now i'm not an apple fan but redpark has something for the i- series of apple products to do exactly what i'm curious about... you can check it on the tech journal.
Now that I spend some time reading and thinking, I might even be able to use my little wgr101 if i figure out a hosts file in the android os to direct traffic through the router. And, if I don't have to wear out the usb jack on the device, all the better.
I think I have my problem fixed, just went ahead a posted this as it might give someone else an idea. Might be a solution that even the op enjoys entertaining... I think op#2 and frayedends are on the right track.

Thinking of performing a hardware mod for USB hosted microsd/bluetooth(Kindle Fire)

Ok, so i'm ordering a replacement digitizer and I figure this would be a good time to try this out.
As you all know, we Kindle Fire owners have neither expandable storage or bluetooth. Hashcode's new 3.0 kernel has the proper kernel modules/support for USB hosting. Instead of having to plug things in every time I need/want extra storage I figure that i'll try and hook up the stuff inside.
So here's what I figure i'll do when I get all the materials:
I already have a mini bluetooth USB dongle that i've disassembled.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
And i'll be getting a mini USB microsd adapter that I can tear apart down to the same type of thing as the bluetooth dongle.
Now, the easy part is finding space to put them, there are a few gaps/spaces that I found for the bluetooth dongle, and placing the microsd adapter should be just as easy.
The hard part is getting the wiring all wired up on the inside, and this is where I need advice/input. Trying to solder the wires to the pins on the charge/USB port would be too hard and risky since they're so close.
I took apart a mini-b USB cable to use the pins to try and hook them up like that some way, but I don't have everything I need yet, so it's just a thought.
Ideas, advice, thoughts and/or comments?
Also, I will be documenting what i'm doing so that I can post a tutorial if I succeed.
I've also posted this in the Kindle Fire general forums. http://forum.xda-developers.com/showthread.php?p=25212300

Main problem with the SD adapter is that many USB SD readers behave badly if you insert the SD when the adapter is live - you need to insert the SD THEN plug the reader into a PC.

Hmmm, thanks for bringing that up, I didn't think of that. I'll have to see about putting a small switch in somewhere if I run into that issue.

Have you looked for another USB pinout on the board?
There might be one, if you can post an hi-res picture of the PCB I can try to find something useful

I was going to try and do that myself, but I couldn't find anything. Right now I ended up scraping off some of the black plastic around the pins at the point that they're going up and i'm trying to solder them alternating the top and bottom.
If you can find other places though that would be great. It might help me out, and it would def help others out if I succeed and write a tutorial.

There's something I don't understand here; won't doing this render the USB port unusable? Don't you need a hub if connecting more than one USB device? Can the USB port provide enough power for these additional devices?

You need the USB hub for power from what I understand. The microsd adapter doesn't require any power and i'm not sure how much the bluetooth takes, but since the other takes none it might work out. If they don't work together then it doesn't really matter to me cause I don't need bluetooth.
Also, about it making the USB port unusable, yes and no. If you look at this pinout diagram here http://www.kineteka.com/microusb-b.aspx you'll see that there are 5 pins. On a USB cable only 4 are used. On a USB otg cable pins 4 and 5 ar econnected telling the device that it's a host and not a slave. When pins 4 and 5 are connected are connected USB will not work at all(So no adb or file transfers, etc.) because the cable is being told it's a host device. Once those two wires are separated then USB will work again because it will see itself as a slave device.

I searched info trought the TI OMAP 4430 documentation about the USB implementation.
(i have to "hide" the link or i won't be able to post!)
Here you can find a block diagram of a reference USB implementation:
h_t_t_p://w!w!w.ti.com/pdfs /wtbu/OMAP4430_ES2.x_DM_Public_Book_V_D .pdf
Section
A.4.4.2 USBA0 PHY Implementation Example
Also, Section
2.1 Terminal Assignments
Shows the pinout of the processor
Table
Table 2-1. Ball Characteristics
Shows the chip connections
The document lists also USB0, USB1 and USB2 but i can only see ball pinouts for "usba0_*" and anything like "usba1_*" or "usba2_*".
So i think that there's only one USB connection and you'll have to solder a USB HUB somewhere between the CPU and the USB connector.

Thanks for the help, but how am I going to solder directly to the processor?
And if I could get the correct pins anyways there would be no need to use USB I could just hook the microsd up directly since the 4430 already has those.
If there was a data sheet somewhere out there for this specific board something like what you're suggesting might be possible, but it's not really the way it is now.
And i've never used USB host capabilities before, but from the videos i've watched people on other devices don't use a hub unless they hook up more than one device.

I see. You are right!
Anyway, i came up with another solution for the bluetooth connectivity: it requires a bit of soldering and a couple of kernel modules (or a custom-built kernel).
You can solder some wires from the serial port of the kindle fire:
http://forum.xda-developers.com/showthread.php?t=1525439
to a UART bluetooth module:
h_ttp://w_w.tdvdesign(dot)com/BluetoothModule/
Then write a script the brings up the bluetooth interface at boot.
In Linux should be feasible, in Android i don't know... maybe there's a praticular framework that needs specific drivers...

**Disregard**This could help with bluetooth if I can't get USB host to work, but that still leaves no solution for the sdcard, which is my primary concern. I've actually gotten all the wires soldered onto the correct pins on the usb port, but I can't get USB host to work for any device, with or without the correct modules.**Disregard**
You got me thinking though, I could probably add a UART sdcard and GPS module on like that. Awesomeness, thanks for the idea. I'll try that out if I can't get USB host to work.

I've also seen a lot of hardware mods that connected sdcards to gpio lines. That could be an option too.
For the sdcard over UART it's possible, but i'm concerned about the performances...

True, true. You seem to have more experience then I do at this. I'll prob buy a GPS UART module and do that. I have the wires soldered onto the USB pins on my Kindle, but I haven't had time to do anything more then that yet.

Thank you
A GPS module will be very useful.
A 7" tab it's portable enough to be carried around and used with a simple car mount...
I'll look for the needed kernel modules asap

I don't really understand why using the usb-port should be a Problem. Just solder your what-ever-you-want-device to the original usb pinout, it's big enough. Solder a rly small switch (taken from an old mobile Phone for example) between pin 4 and 5 to change host and normal mode. Finally, if u need more power there of course is a battery inside the Kindle, get it from there
I'll receive my Kindle in a few days i hope (u can't buy it regularly in germany...), will play a bit with this stuff

The UART modules are only an idea, the main problem with going that direction instead of USB host is the drivers the modules would need(They all usually come with generic ones, but they would need to be customized for Android). I have very limited code/coding knowledge so I would need alot of help or soeone to do that part completely. I was going to pm Hashcode for help if I decided to try out the UART modules. Also, i'm unsure if more than one module can be used at the same time.
Like I just posted in the thread i'm still waiting on some stuff to arrive to actually get started on the USB host attempt. I have the wires soldered to the USB/Charge port pins, but since I don't have the microsd adapter or any more spare cords to rip apart I can't go further. I ordered about 10 different mini microsd adapters to take apart and see which works out the best.
Other people have USB host working, so shouldn't be difficult. I've just never used USB host before so i'm not real sure of what to expect.
The only downside is that there needs to be a switch of some sort somewhere to disable USB host so that adb/storage will work. I'm trying to think of something a little more elegant that having a huge hole in the case with a switch protruding out of the side. I'm going to go searching for some solutions and a super small switch.
All the UART GPS modules I found when searching "uart gps module" on Google are mostly from India and are between $30-50ish, the receivers look to be about the size of a quarter.

I decided to look on Sparkfun and adafruit and i'm glad I did, it looks like they both have some modules, but I haven't looked around and dug through them yet.

All the optimism aside i'm not all too sure that we could get the GPS UART module to work. From what I see (First picture: http://forum.xda-developers.com/showthread.php?t=1471813) the UART output that Hashcode put into use only has two GNDs a TX and RX. The modules that I found all look like they need 8 connections. Adafruit has a nice pic of the connections labeled here: http://www.adafruit.com/products/746
If you're talking about microsd UART modules, as mentioned in the thread I created, someone made the point that it wouldn't make much sense because speeds would be way too low.

Just curious about the status of your progress.....

USB Host support

It pains me to do this, as I was hoping B&N will step forward and release an OTG/USB Host cable. The hardware is certainly all there.
But alas, they are sitting on their hands again, so I have no other choice but use this software override kludge again.
All for the better most probably, as I suspect when they do release, it'll cost some outrageous amount of money, just like what happened to the HDMI adapter.
If you want to try it yourself.

After reading around, one can use a battery pack with pass-thru USB function to connect high-powered devices like a USB HDD. Continuing this line of thought, it should be feasible to connect said battery inline to an unpowered USB hub, and convert said hub to powered. Am practicing some Google-fu to find a decent pass-through USB battery now.

Continuing this line of thought, it should be feasible to connect said battery inline to an unpowered USB hub, and convert said hub to powered. Am practicing some Google-fu to find a decent pass-through USB battery now.

there are tons of battery-powered hubs for mobile devices, which seems to be a neater solution than combining a usb hub with a battery.

Would you mind providing some quick links, or whatever search keywords you used? Mine turned up zip:

Try "battery powered usb hub"

I was hoping you have some actual models in mind. Your key terms resolve to the same blank wall. There are plenty of "battery hubs" shown, but AFAICT all of them are AC-powered hubs that can charge battery-powered devices. The need for a portable (battery) powered hub isn't new, and I've searched for it before. I was thinking of DIY, but a hub + inline passthru battery pack looks to be the least hassle at this point. Again, would appreciate any more integrated solution you know of.

Welp nothing that some window shopping can't cure, as me sis would say.

Well, the very first link on that google search is to this amazon item: http://www.amazon.com/CyberPower-Mobile-Battery-Powered-CP-H420MP/dp/B0002UQALQ/ref=pd_sxp_f_pt
which is eaxactly a usb hub with AA batteries. Granted, it's no longer available for sale, but there are more of those, I saw them when I last looked a couple of years ago so I know there must be more.

That seems a lot of power draw to be practical, unless a chunky hub to last very long.

Did you measure it? Does not seem too bad in my testing.

Just my looking at the draw having two things hooked up. If you are using one usb drive and no other devices, it should last several hours. Better than taking the load via the tablet battery. Sharing the drain love is good.

so the gender changer usb host thing only works with cm10.1 and not on stock?

This is correct.
For stock you need to have this special cable that B&N never made available (but certainly had plans for).
Shoehorning a new kernel into stock is too much of a hassle too.
But if you are an enterprising individual, you can trace the id pin on the pcb to see where does that connect in the connector and make your own otg cables, resell for huge amounts of money and profit

[Q] asus transformer t100

hey guys , i saw in a review of this new win 8 tablet, the guy said the bay trail cpu can run android with no problems, i am totally buying this tablet, but has anybody tryied to install android in it, or along win 8? thanks guys..

Someone would have to compile Android x86 for it. I'm not sure how well the current Android x86 isos out there would support the hardware. You could always run Android x86 through Virtualbox, the downside being performance would suffer since your tablet would be running Android on top of Windows.

I dont think they have shipped to consumers yet.
For now you have virtualbox (or VMware, I get better performance with VMWare but virtualbox is more straightforward) and android-x86. Or "Jar Of Beans" or bluestacks. I think a regular ARM build of android has been tried in QEMU too but on a bay trail this will be unusably slow, heck, its near enough unusable on a god damned core i7.
Bay trail doesnt have the operating system lock that clovertrail had. So yes, it should be able to boot android-x86 natively, but android-x86 doesnt support all touchscreens, bluetooth or wifi, chances are on the t100 it wont work properly. Android-IA is far better than android x86, but is device specific so you will have to hope that there is an Android IA build for the t100 *or* someone makes a compatible build of android x86 for the t100. It is theoretically possible though.

Might try to take teh dock apart and see if I can fit a battery in it. I have a couple portable charges that go up to 12000mah
I might wonder if I could fit one in there maybe a 5000mah or a 8k. I might have to take mine apart to see how everything is laid out.
But on a side note I still need to get one. Anyone know where a 32GB one can be bought?

with flat batteries, and some sanding maybe? but you'll either sacrifice the usb port, or have to integrate a usb hub in there somehow, or just wire the batteries in the data pins only... I'm interested in that too, may look at hardware mods once the software mods get going enough

Wiring into the data pins will kill the USB controller. Guess you probably meant the +5v and GND pins.
Do you know if anyone has reverse engineered the dock connector pinout? Chances are you will not be able to wire a battery into the system from the keyboard on the USB port.

I was going to use the interface form one of the ultra thin portable chargers that has a 2amp output. I was going to use the USBin it and mount it on the opposite side of the current USB 3.0 and there may be room on the sides of the touchepad. I will try once i can get my hand on one.
I was then going to use a thin and short usb cable I made to wire it to the USB port on the tablet part that I can plug and unplug when needed. .

How about trying a dock from one of the Android transformer series? they all come with built-in batteries..
I was thinking it might work if the connectors and latches are the same!

Confirmed to not be compatible.

Asus will release a T100 with a modified keyboard T100TA-DK007H - 64GB eMMC with 500GB built internally. Makes you wonder what other things you could pop under the hood.
As for running other OS, seems booting is way to complicated at the moment. Anyone tried running Gennymotion VM on it yet?

Screen question
Hello!
hope im at the right forum ... i have been using my t100 for 2 days now and im in love with it XD
i had the slow charge problem with it but 2.20 bios fixed that ... now im using 1.2m cable that came with my logitech keyboard (the cable trully is of top quality) and original charger (need to try it out with my s4 charger) and it fills up in about 4 hours.
My question is about the screen ... when i close it when its in the keyboard ... there are only options to "shut down", "sleep" or "do nothing" ... is there a way to turn the screen off while the tablet is still turned on ... like on laptop if you choose "do nothing" it will stay on but the screen of the laptop will shutdown.
Cheers!

Sure man, just go to control panel, power management, change settings, and here set time to go to sleep after 4-5h. Then, change advanced power settings and make screen to turn off after 5 mins. This way, you can leave PC tuned on, while screen is off...

T100 Slow WiFi with External Monitor
When I connect my T100 to an external Monitor then wifi becomes extremely slow, 1 - 2 mb/sec and much of the time I get the unable to connect msg in the browser.
Windows shows that I am connected to my wireless lan.
It only happens if the cable is connected to the monitor. Connecting the cable to the T100 without a monitor does not affect the wifi speed.
It only happens if the t100 is set to display something on the external monitor. If I set it to internal only then even with the external monitor connected, then the WiFi is fine.
Monitor is Dell U2410. I am using a minihdmi to hdmi adpapter and a three foot hdmi cable.
I was completely updated with all windows updates. Not all ausus updates installed. I did install the latest bios update, 220 I believe.
I also tried rolling back to a system restore before I updated all the windows drivers but that did not help.
Can someone else test their network speeds with an external monitor?
Any ideas how to fix?

T100 Slow WiFi with External Monitor
I tried a different WiFi access point in my home but that did not help. Windows shows plenty of signal strength for the WiFi network connection, but I just get a bad data rate.
Without an external screen connected then the WiFi connection is good. It is much more reliable than for my Old Asus Transformer Infinity TF700 tablet.
If I connect a Unitek wired ethernet converter to my USB port and use that for networking then the data rate is ok, so the problem is definitely related to WiFi. I am wondering if anyone else sees the same behavior or if it is just my device.

That sounds really really weird, shouldnt happen though.

I've read there's a chunk of metal as counterweight located in the keyboard. Asus took that out and put a 500Gb HDD instead. Maybe you could put a battery instead?

It is in fact a counter weight and I have confirmed that removing it will cause it to fall over when opened. LOL
As far s running Android... why? Android makes a great mobile OS and works fine on tablets, but this particular device is a desktop PC, in tablet FORM.
Full Windows, not RT, MS Office included, etc... It is part of what makes it so appealing... While I am a huge Android fan, to put that on this device would seem like a downgrade to me.
I would love to see a keyboard base with extra storage and battery though...
