I bought an unbranded OTG connector for my Z1. I connected a few common devices i.e. USB flash drive, mouse, wireless gamepad,
All worked. But then I tried all my mobile hard drivess, both USB 2.0 and 3.0. Didnt work at all. My z1 couldn't even get to recognize the device connected. The LED of the HD lights up so its getting power. I'm not sure if its getting enough power.
The OTG connector I bought was the long one. The cable is about 2 inches long. I'm not sure
if you call that the long OTG connector.
Any advice how i could I make the Z1 work with my mobile hard drives?
TIA!

What if you test with a drive that have ac adaptor?
I think you pretend too much from a phone device. I am sure there is not enough power to make it run with the Z1. The solution is to use double usb, first to Z1 the second to the charger or another USB, to power up the HDD. Also like @RHBH said if you use a HDD with the AC adapter and it's working that will clarified all.
Oh sorry I tried it W/O the AC adaptors types hard drives. The small WD passports ones.
Shouldn't it be working since the lights are on and the mobile seems to be running?

Enough to power up the light but not enough to do his job. The reasons can be many but if any HDD with AC charger working and all type of storage, the answer is just one.
The OTG specs of the z1 and xz are the same, I can tell you that if you use a powered usb hub between the disk and the phone it will work just fine.
The power delivered to the disk is simply not enough.
I know the power output can actually be tweaked, but you run a serious risk of destroying your phones usb port.
Or maybe his HDD is not formatted in FAT.....
Well that is odd if I try to format it a 1TB hard drive to FAT. Isnt FAT already phase out in terms of drives over 40GB?
And about the power requirement, OTG + mobile hard drive works on other smartphones.
I bought my C903 online btw. Also, I have gone to Sony a awhile ago and tried to attach my mobile hard drives. None worked.
So I think that confirms it.

I know you are disappointed but try to power up the HDD and see if working. This is not the solution but you get the reason why this happening.
I got 2 mobile HDD and I will test them on my Z1 and I will post the results, when I get the phone from Sony Center, but even if mine will not work I can expect that because is too much but I will be happy too if will work. I let you know.
BTW, can be even the OTG Cable, try different one, I got very heavy problems when I bought one really cheap.
You got a Clamp multimeter buddy? I don't know but I would like to assume there's not enough power to run your mobile HDD. If you do have some way of checking the amperes or wattage output of the OTG of Xperia Z1 and compare it against the required input of your mobile HDD maybe that would point out your issue. Having a non compatible filesystem format would still prompt your phone about a corrupt drive and would ask you to reformat it so it shouldn't be the issue. And as far as I know Xperia Z1 already supports exfat am I right? Or maybe you could at least just format the HDD to fat32 is you still want to check it out since fat32 is supported by default by android.
Depends in the size and usb 3 is not supported unless it had external power and as for format it has to be fat32 or exfat or it won't read out of all my android devices my Asus transformer where the only ones that supported all formats and sizes of hard drives because the docks have tons of extra power.

really ? why would they put a usb hub that does not work with the shift... seems weird !
everybody here is using the usb hub without any issue I believe.. because they would have complained earlier
The (much bigger) MacBook AIR also has only one USB port... and Apple doesn't include an 3port-USB-Hub with embedded ethernet port - the shift does.
But there are of course also technical reasons (besides space): Power! An additional USB Port would require additinal power (up to 0,5A at 5V) - thus, the internal power system must be bigger sized for this (and an "oversized" internal power system means: Inefficent under normal operating conditions).
And remember: Most USB Disks draw more than 0,5A from the USB port, especially at spinup time...

when i'm in office or at home i use an external power cable directly connected to the htc hub. but is not comfortable.
and when i'm out or in others places i can't use external power cable.
in my opinion not comfortable anymore.
Isn't the small USB port at the back of the Hub just power in? I didn't try yet, but it is obviously a IN port.

These usb options are great but I think you missing the point of the shift.
The shift is supposed to be a portable device, are you really going to bring all those wired devices with you? Do you really want to be connecting all that up each time you get to work or your desk at home? everyday?
Why not use bluetooth devices?
keyboard and mouse -bluetooth for sure.
Same goes for the pens, portable scanners and printers almost all of them can be found with a bluetooth options.
Hell I even use bluetooth devices for the serial connections on the routers and switches I work with.
Now your external dvd and hardrive to replace those you have to get creative -
For home and work I always map a drive from a desktop machine.
On the road you have a couple of options with flash drives at 16gb for $50-70 bucks do really need that old external harddrive that uses two ports?
32GB flash drives are now as low as $150. Quite few dvd's you can fit on that!
If you really want to be free of carrying stuff around sign up for sugarsync or some other online service and never carry your data again.
I almost never use the external usb hub that came with the shift. It is a last resort item for me, destined for the bottom of the laptop bag. Wifi, 3g and no cables will always be prefered over that thing.
You may like sticking with usb cable/dongle devices but consider switching a few out for more wireless solutions and I think you will like your shift a whole lot better. That rats nest of cables in your laptop bag will shink as well!
I am not knocking you question or the advise others have given just offering an alternative.
My dream is for somebody to find a way to charge the battery on my shift without a cable connected then I will die a happy man.

if you put your mobile phone power cord in the htc hub will be feeded up.
now when hub is feeded you can put more hdd or an external dvd. but if you unput power cord the dvd or the hdds not work yet...
Did you plug a power supply in the mini usb plug on the back? This is a powered USB hub.
i think htc could of added more usb ports but the biggest problem was the space. more usb ports could of made it bigger. never disassembled or looked at the disassembly pics close but im guessing there is no more room really.

Ok, in theory Galaxy S 2 supports USB On-The-Go which means, it can be a USB host device for things like pendrives, digital cameras etc.
Granted of course, that you have the necessary cable.
Has anyone tried this feature?
Also, does the connected device have to be formatted as fat32?

Hi there,
Got my £2 cable from Hong Kong (ebay purchase today).
Works great - even runs my 500GB HDD (this has to be plugged in to operate anyway - not sure USB powered HDDs will work).
If anyone's interested, the item description was:
Micro USB Host Cable for Nokia N810 OTG on the go N 810
No mention of the SGS2 - but I can verify that these work just fine!!!
Jamie
Any Nokia compatible OTG cable seem to work. I've successfully tested several different cables (all from eBay) with usb sticks, optical mouse and usb based memory card reader. However, usb based wifi sticks, fast ethernet dongle and tv-card didn't work. We probably need some new drivers and possibly more power (an usb hub could fix this).
I bought the Nokia USB OTG adapter too. With FAT32 Sticks ists working. But without NTFS support it is nearly useless for me.
umm...i have a nokia n8 and i took off the OTG cable that came with it before selling it in favor of buying a new Galaxy S 2.
However, the nokia OTG cable is perfectly rectangular, whereas the Galaxy S 2 cable connector is a bit "broken off" two edges, hence, using them is impossible together...but i managed to get them to work (in the shop where i tried the Galaxy S 2 at least, i didn't buy the phone yet).
I used a rasp, and filed off the edges of the Nokia OTG cable carefully to match the "broken edges" as the Galaxy S2's connector shape...took that cable to the shop where there is a working Galaxy S 2 unit, and connected it with a flash disk on the other side aaaaaaaaaaaaaaaaaaand......it worked !
If you have the caution and a rasp, i think Nokia's OTG cable should work too..they're cheap off ebay too, aren't they ?
Just ordered one of those off ebay (The Nokia N8 compatible one). Would receive it by tomorrow. I hope it works!
Here is mine ****ty review of USB mouse, USB keyboard and USB lamp.
http://www.youtube.com/watch?v=xQn1DCA0PRQ
here's mine, got it also from ebay.
If you can't get it to recognize USB mass storage I would suggest using USB Mass Storage Watcher: https://market.android.com/details?id=com.skidmrk.umswatcherotg. It will let you mount any type of external storage (NTFS, FAT 32/16, EXT, etc... It's free.

Could anyone shed some light on the subject from their trial and errors?

As stated above it will Support a hub ..
But with limitations on devices.. you will not be able to say use a full size usb hard drive while connected to a keyboard and mouse at the same time. I belive this will be to much power . look at the amps and the devices are pulling and compare them with with the Hub says its needs are.. But this is common on any usb hub. they make some that you can use with or without power cord.. I have one that works will i think its a cheaper belkin brand..... very tiny and have 4 ports..

Hi people,
I read in a review that you can connect an external hard drive to the nexus 7 (the usb powered ones) via a USB Host Cable.
Could any of you tell me if this is correct or not? As i have an Archos 80 g9 and i know it cant do it off the micro usb only the USB 2.0 slot it has.
Thanks a lot for the help

Kurpter
Yes, it is possible but you may need to provide external power to the drive. Use a powered usb hub or something like that. The Nexus 7 most likely won't be able to output enough current to power a spinning drive.
Ah ok, so you are saying that you plug the usb host connection from the nexus to the usb hub and plug the hard drive in to another port on the hub?
I just want to know if this works as 16GB isnt much space when you want to take it on a trap to watch films.
cheers
you need to be rooted. my understanding is flash drives or micro sdcards are good to go, not sure an external hd will work unless powered as previous poster alluded

Hi. I decided to use a wireless drive to store all of my music, movies and documents. So, I purchased the Seagate GoFlex Satellite Mobile Wireless Storage. You can use with Android or IOS devices. I love it.
Yes, its a no-go out-of-the box connecting to a USB thumb drive or a powered HD with a microUSB OTG cable. This doesn't really surprise me, though, because they would need to dynamically detect the device type and mount it on the system. What I haven't tried is a USB keyboard. Anybody do that?

I just plugged in a full-sized USB keyboard using my OTG cable and it works fine. I can touch type, use the cursor keys including ctrl+arrows to skip words, bring up menus with the context menu key just to the left of the right-hand ctrl key, etc, etc. I'm sure it must be using up my battery at a faster rate, though.
Edit: It's just occurred to me that there's a problem with using a USB keyboard to type when the N7 is in portrait mode: finding a stand to hold the tablet upright at the right angle when the USB-OTG cable is sticking out of the USB port at the bottom of the tablet.
Mind you, it's great being able to type at full speed without a soft keyboard hiding a large chunk of the screen.

You can get OTG cables with a right angled micro-USB plug on them, which might help your stand problem. I have one on its way as I was concerned about knocking/bending/snapping the straight plug when its sat on my lap in portrait mode.

Or, just turn the tablet upside down so the cable is pointing up. The display will rotate appropriately.
I think but not sure that you'll want cm10 for the rotate from any angle thing...

Without a custom kernel, the external hdd won't work with Stickmount or NMI if it is formatted NTFS. I haven't actually used NMI, but others have posted about the NTFS issue.
Hello, I want to know how many USB-Devices you can use, assuming you use a normal USB-OTG cable and a cheap USB hub (without external power supply). How many devices can Android theoretically recognize? Is it possible to use a keyboard, mouse and USB stick/HDD? Would be cool if someone could try this....

Android can recognize as many devices as there are USB hub ports, check out this video (I know it's for the Galaxy S3 but the idea is the same) specifically 2:50 seconds on using a USB hub with mouse, keyboard, and other accessories.

It should work the same with a non powered USB except that power will be drawn from the tablets battery power instead of an external power supply.

I tried for a couple of days to tweak the implementation in my kernel mod so that multiple usb drives could be mounted, i took pointers from my s3, but it seems samsung have further mods, probably to vold in their own brand devices and i couldnt for the life of me get it to recognise more than one device on the n10.

I think a powered hub is the way to go if you're using multiple devices as I'm sure there's a limit as to how much power the USB port can supply to your devices. You may find that several flash drives work fine together with a powered hub and I would try to get one with a 5v 2a adaptor if possible to give you flexibility to plug virtually anything in you wish simultaneously

Without a powered hub the deciding factor for how many devices you can use is going to be how much power each device draws... And that will vary from device to device.
I, personally, have had a keyboard, wireless mouse, flash drive and Xbox controller all connected at the same time with an unpowered hub.
Yeah, multiple flash drives and especially external USB spinners tend to draw a lot more power. Input devices (keyboards, mice, joypads) use very little power but a combination of several may be enough to give you intermittent operation and a few issues.
Usually when people start connecting keyboards and suchlike, they're going to be at a desk so should have access to a wall socket anyway; powered hubs tend to make multiple devices work better as it's a stable power supply available.

do you think the n10 provides less poser on its usb bus than a pc or laptop? i think its able to provide the same power as my pc and 3 usb sticks + wireless keyboard/mouse work perfectly with a non powered hub...
btw. i just tried the hub with 1 flash + mouse+ keyboard, works perfectly (aosp rom 2nd dec version i think)

I'm pretty certain that it does provide less; I have a 2.5" WD Passport HDD that is bus powered. My XOOM used to power it, my PC and laptops power it, but my Nexus 10 doesn't. The N10 certainly isn't pushing 500mA in host mode cause the drive can't even spin up on the power its receiving. It's a real shame cause I had hoped to power the HDD directly.
What I need now is a nice small powered hub that I can power from an emergency phone charger battery, like my Mili Power brick.
