*This is only a reference/information thread for those who want to use OTG feature on our 2011 xperia phones, for your convenience.
(For that Sony Ericsson didn't tell you how to use that feature.)
Information for xperia mini, mini pro, LWW and Active.(since they share similar chipsets)
TESTED ON GB 2.3 Stock rom with wt19i.
1. USB OTG support is native on stock roms.
2. Almost every USB keyboard and mouse can be used with OTG.
3. Some special keys on the keyboard may NOT work(such as volume up/down buttons).
4. Key bindings may NOT work. e.g. Ctrl + C won't work in terminal apps such as connectbot or terminal emulator. Consider twice if you want to use keyboard for terminal.
5. To use USB flash drives, you have to use OTG helper from shardul_seth from:
http://forum.xda-developers.com/showthread.php?t=1588979
6. (with OTG helper) USB drives will be mounted @ /sdcard/usb_stick_1/ (or something similar)
7. USB hubs CAN be used.
8. Portable hard-drives can be used although it needs external power source.
9. Using these USB devices with your phone can DEPLETE YOUR BATTERY rather quickly.
10. Pen tablets won't work. (Tested device: Wacom Banboo)
11. USB card readers might NOT work. (Some do, some don't. I tested a card reader with multiple slots(MS Pro, microSD, SD) and my wt19i failed to recognize it.)
12. USB flash drives larger than 16GB might NOT work. (As reported from Taiwanese forums.)
13. Some USB joysticks will work, some won't. (No drivers for Android
I will keep testing USB devices though. Thread will be updated in the future.
Attachment is my own wt19i with an USB keyboard.
Preserved for future use.

USB joystick work like a charm, I've tested a thurstmaster 8 button on my mini pro!
@paacoo Thank you. Information corrected now.
p.s. Tested that Playstation 3 controller wouldn't work
Other devices
Hello all
I have tried WD self powered 1Tb HDD the trick was to connect a hub with double USB cable, one to the phone and the other to a battery or usb charger, worked correctly, I think I can browse all the drive content.
Recently I bought a multi card reader branded as Manhattan that support SD, micro SD, MMC, etc.., plus 3 usbs and worked. I can read my SD/microsd and read/write files.
Also I tried wireless (RF) mouse/keyboard branded acktec and worked great.
If you are interested I can tell you the product number.
@edgar0204 Thanks for your reply. I think I'll start a list for unsupported devices then

@aznrogerazn: I"m sure in that Android compatible only with HID devices. I"m unsure in that PS3 controller is HID-based, but take a look here:
http://www.codeproject.com/Articles/23634/Wired-PS3-Six-Axis-Controller-Using-USB-HID-as-Inp
@x.x.x.Peria The reason why Playstation 3 controller fails to work is that the phone cannot provide sufficient power supply. With proper programming and enough power, it is supposed to work. It can be used on the phone with bluetooth, however.

There are no hidden features on our phone.
USB OTG feature is known already on Live with Walkman, announced aswell on official white paper.
By default(and officially), OTG support exists only on LWW, but with certain workarounds, it is possible on other devices aswell.

Knowledge for homemade USB OTG cable http://forum.xda-developers.com/showthread.php?t=1092493
I don't found posts about atom bomb yet
I made a homemade USB OTG with the help of this tutorial, and works like a charm.
:highfive:
If I use an USB HUB with external power, it will work? My target is use an USB HUB with external power to supply energy for a mouse, a keyboard, a pen drive and my phone. Or just to reduce the battery consumption. I know HUB powered by USB works fine.
PS: with OTG cable, my homemade one: kingston pendrive 8GB works, lenovo mouse and keyboard works, leadership mouse and keyboard (with a nice number of special keys) works, Bright wireless mouse with usb adapter works, bluetooth usb dongle don't works (needs driver), and with a USB OTG cable you can recharge another phone haha. * I'm using ICS at St15i.
USB hubs with external power source is working as reported from Taiwanese forums. You can only use one flash drive on the hub at the moment though.

Interesting.
With powered hub, I connected a PS3 controller and reading the kernel log with dmesg, seems to be recognized and installed but don't works and starts to charge, without my phone at hub the controller don't charge. Other devices work normal, and the phone is not in charge mode :silly:.
If anyone have idea to tests, I think I can do for help.
Thanks for the thread aznrogerazn.
Can anyone confirm if this works on MiniCMSandwich Lite? I don't have an OTG cable but I'm gonna buy one if and only if, it's working. Gonna be a waste if it doesn't.
@GregyrioAxiaMagno PS3 controllers can be used on bluetooth mode. You can google the method if you like.

Thanks aznrogerazn, I have the Sixaxis app working good, is a nice app is it?
But, check this out, I have a nice news hahaha. I managed to work the PS3 controller by USB. So: I have a 7 ports powered hub, and it can be powered by usb also. I plugged my otg cable in Android and the cable at the HUB, then I plugged the power cable, after this, I connected the PS3 controller at HUB, the lights at the controller will blink if in charge mode or blink only once if the battery is full, and unintentionally, I hit the button with the PlayStation logo, and voilà: the controller works! I noticed what the touchscreen gets a strange behavior... I saw this same behavior when a friend used an non oficial usb cable to charge the xperia x8, an ordinary cable... like if the touchscreen got messy. But the controller and the rest works. So give a try, with a powered HUB and plug all, then hit the PS logo. I noticed also what the usb host mode can be disabled sometimes, is just restart the phone or plug a mouse or something to get work again.
I will make a video maybe or take some photos in another thread.
EDIT: The strange behavior of the touchscreen is caused by the power, I mean, when I connect the power cable. I think this happens because there is no filter of energy in the circuit. Maybe a high quality HUB solve the issue. The touch screen become normal again when the ordinary power cable got disconnected.
EDIT 2: About the crazy touch see this http://forum.xda-developers.com/showpost.php?p=10206146&postcount=8. The power cable of the USB HUB is an ordinary 5V 1000mA, thats is the problem.
EDIT 3: I made a video but I won't open a new thread xP

Wiki made it sound like the USB host feature that is available in ICS, flash drives, keyboards, mouse and such..
its a cool feature that allows a usb-phone connectivity. in simple we may plug and use pendrive, ext hdd with our phone, and access the files in those drives.....

Short answer.. Yes
Lapdock and hd hubs have usb ports already configured.
You can also make your own adapter by purchasing a usb otg cable and modifying a generic usb hub. The otg protocol needs to have 5v returned from the hub to the phone.
There are a couple of forum posts related to that.

that's of course possible ; atrix is a great gadget and capable of many things .
here we go:
1. first get a USB OTG adaptor cable.
2. make your 5v electric-powered USB hub ready.
3. make your USB cable ready (usually USB hub is good for mini USB cable; therefore, you need to obtain also micro to mini USB adaptor too.)
everything is ready now.
4. connect USB hub to power.
5. connect your USB cable to USB hub.
6. connect your USB OTG to your atrix.
you are all set-up.
here we continue...
connect your keyborad, mouse, usb flash, etc. to the USB hub. Voilaaaaaa mouse cursor and the keyboard as well as the usb flash are all visible on Atrix.
Have fun and enjoy it...
In case you wish, search for youtube for "Atrix OTG support"; you will come across many vidoes that verify what I just briefed above..
on top of all, get a neptop.apk and connect to the HD TV via HDMI cable and taste the ultimate pleasure of WEBTOP

I am not sure at the moment nor can I verify where I see the USB as I am not at my home desk now, but if I am not mistaken it presents itself or you may find it under "files". Should you have not stock "files" app, then refer to "usbdisk..." folders under "mnt".

I just got it working in a Custom Blur-based Rom ([ROM][GB] NOTTACHTRIX 4G (v1.9.0) Updated Mar 11 2013).
I used a Power charger connected to a Innobo (average quality) USB hub. Then I connected a mouse and a USB memory to the hub plus the Atrix (via OTG cable).
The phone recognized the USB memory without any problem and the mouse works really fine.
I have´n´t tried a keyboard yet, but I guess It will work as well.

just ordered one on ebay (only an adapter from normal usb to micro-usb) for 1$.
Along with the otg cable u also need a usb Wye cable...the need is to provide power (plugged into the wall) for the usb hub (which u will also need ). Not Neuf power and the drives will not mount. Getting a solar powered usb hub cuts away the cables and detached u from the wall...I got mine on Amazon for bout 20 $. Totally worth it.

Thanks to a recent video by reverendkjr on Youtube, we now have a confirmed USB OTG method for CM9.
http://www.youtube.com/watch?v=Nc7tlPwFQpg
This has lots of potential and since I did not see much talk about it here, I decided to create a thread with what you need to buy listed in reverendkjr's video and what works. I would recommend only buying from Amazon Fulfilled sellers as they are backed by Amazon's return policy. All 3 items only cost a little over $10.

OTG Cable With Female MicroUSB (Allows you to use any microUSB charger as the power supply)
http://www.ebay.com/itm/130740524313?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649
OTG Cable With Male Full Size USB (Allows you to use any power supply with regular USB port)
http://www.ebay.com/itm/Micro-USB-H...i9100-S3-i9300-i9220-i9250-XOOM-/140825132367
You can use whatever source of USB power you want including a wall charger, but I bought the 2AA battery powered supply above and can confirm it works.
Compatibility List:
-Multiple USB devices will work if you use a USB hub. A non-powered one works fine for me since you will already have a separate power source.
-USB keyboards and mice work fine including all basic functions like scroll wheel on the mouse, num and caps lock on the keyboard.
-FAT32 formatted flash drives will mount by default under "/mnt/usbdisk".
(Added September 7th)
-If you want to mount NTFS drives or multiple flash drives, download Drive Mount. This software will mount drives under "/mnt/sda1", "/mnt/sdb1", etc. I can confirm it works for multiple drives and NTFS/FAT32. It was removed from Google Play so the apk has been posted. If anybody has had success with other NTFS mounting software please post your results.
(Added April 6th)
-I tried a Rosewill USB SATA/IDE externally powered hard drive reader and was able to mount a 400GB SATA 3.5" HDD using Drive Mount. Just to see what would happen I tried a SATA DVD drive but Android doesn't recognize it and probably doesn't even support the CD/DVD file system.
(Added April 7th)
-USB card readers will work, but I've had mixed results.
USB Device Info:
If you want to diagnose items and see some info about what the Touchpad is detecting, download USB Device Info free from Google Play. Everything shows up under the Linux tab. This shows some useful info about devices including current draw, device identification, etc. I tested it with a USB hub and a few flash drives and it successfully showed entries for the hub and the flash drives. It wont tell you if Android has drivers for the device, but merely IDs the device(s) confirming the connection if working.
(Added Dec 9th)
A plugged in USB OTG adapter will show up as "Qualcomm On-Chip EHCI Host Controller" under the Linux tab regardless of whether or not power is present. This is a good way to see if you have a working OTG adapter.
Flash Drive Unmounting Issues:
Flash drives are called an SD Card when mounted. There is no option to unmount a flash drive unless you use Drive Mount, so if you notice SD card removal error messages they are referring to your flash drive and not the Touchpad's internal memory partition that is mounted as /sdcard.
When a flash drive is removed or powered off without being unmounted, its common to get a "android.process.media" force close, just tap OK.
Charging:
You will not be able to charge via micro USB while using OTG even if your power source has enough current. You can charge via the Touchstone just fine. Knowing this, you can set up a really nice docking station by using the Touchstone as a stand/charger and then using the microUSB slot for peripherals like a USB keyboard and mouse connected to a hub with spare ports for flash drives, etc.
(Added September 7th)
Insufficient Available Bus Power Fix:
If you get this error, I haven't yet, some users have had success using this app posted on Rootzwiki.
I didn't feel like buying anything and already had some things laying around so I modified an Adafruit MintyBoost to accept a device via usb, add power, and continue on down the line...
Really all I did was solder a usb cable onto the female USB port on the MintyBoost, drill a hole on the other side of the tin and feed it out. The card reader conveniently fits inside of the mint tin so it's a pretty compact package.
The only down side I've noticed is that it also charges the TouchPad (the batteries will die quicker) and continues to send power to the card reader after the OTG cable has been unplugged from the TouchPad.
Excuse the crappy pic. I really don't feel like taking a better one.
I could never get the OTG cable to charge the Touchpad, I always thought when the Touchpad sensed OTG (grounding on pin 4) it refused to take power. You can disconnect the +5v Vcc to the Touchpad (red wire) on your OTG cable and OTG devices will still work.

I came to the same conclusion some days ago ,touch pad can't be charged using org cable,needs a regular micro USB cable and the barrel AC charger.I did many tests but having otg devices working and really charge at the same time its not possible,it seems like charging but its not.

If its provides its own 5v power it would likely work, but I don't really see anywhere for an external power connection and it looks too small to house a battery.

For whatever reason, when I tried that the card reader wouldn't initialize. Once I connected the +5v from the OTG it'd light right up...
After it lit up I could disconnect the +5v and it'd stop the "charging" notification on the touchpad and keep working.

Then it should work fine as the Touchpad uses a standard OTG pinout, it just doesn't provide power so if it has a way to provide power to devices than I see no reason why it wouldn't work.
quick question that i didn't see answered above :S can i use the otg cable adapter without another power source (like can touchpad power it?)? Saw it asked above but didn't see anyone saying that the power source is required :S
kind of want to plug a usb flash drive into touchpad so I can type documents when I'm on the go and switch to computer. don't want to carry another power source either :S

No, the Touchpad doesn't provide any power for OTG devices which is why you need to supply it power. The cheap USB charger I linked to in the original post will work fine for a portable power supply if you don't want to build something yourself.
And it also appears you can't just plug the other USB into the wall?

Nice and cheap and the best part it works.
USB Hub works...sort of.
I tried this with a cheap USB hub I bought. I had bought it for my laptop and made sure it had it's own power supply to keep the load off my laptop, so I thought it would be perfect for this. Nice try though.
Turns out it needs 5V from the host to activate as well as the additional external power supply. Just fired it up with my TouchPad connected via a Y-Cable and my Laptop providing the 5V to fire it up. Works like a charm.
As yet to find out if it works with my travel charger providing the 5V and no external power supply plugged in, and how many devices I can hook up. It's got 7 ports so I suppose the supply might be useful then, but do I really need to hook up that many devices? Otherwise...pointless. Back to the drawing board I go.

Hi there.
I got my Galaxy S3 about 3 days ago and love almost everything about it.
I've been experimenting heavily with USB OTG, and it's such a great feature to have. I have got a Mouse, keyboard and USB flash drive all working over the USB OTG cable. I can also get the Mouse and Keyboard connected at the same time over a USB hub. However, USB flash drives refuse to work over a hub on USB OTG, even though they work directly from the phone to the USB. This is pretty confusing to me, considering two higher power devices work over the hub.
I've tried two different varieties of hub, both giving the same result and have also tried two flash drives. I'm using an un-powered hub and I honestly don't see how just because I'm using a hub the USB Flash drive isn't working. There is no way that it can have a higher power usage than a mouse/keyboard at the same time.
Just to note, I'm using the hub unpowered externally, it's going directly into the phone. I can't seem to find the power cable to try.
I have the UK (GSM) variant of the phone in blue and am running on the Stock 4.0.4 ICS firmware (i9300XXLF2) and haven't tried to root or anything.
Could someone suggest what might be the issue I'm having, or some things to try?
Thanks
Its a common IT issue that not everything works through a USB hub. Or even US extension cables.

It works through it regularly through a PC.
Both USB sticks. And I've seen a video of someone doing it on youtube. I've also tried both FAT32 and NTFS with the same result.
Can you explain your exact set up please?

Samsung galaxy S3 connected to a small unpowered USB 2.0 hub, via a standard USB OTG cable. Connected to the USB hub is a single USB flash drive of which I have tried a 16GB (14GB actual) stick formatted in FAT32 and a 128mb stick in FAT32. When I connect the OTG cable, it's recognised by the phone. I then attach the USB hub and nothing is recognised, but it is infact working. I can confirm that because I've tried both a mouse and keyboard separately and at the same time through the hub. I have tried another hub with the same result. I then unplug those and put in the flash drive, the red light on the flash drive flashes for a bit and then dies, nothing is picked up by the phone.
Is the hub connected to a PC or not?
Are you saying:
Flash > Hub > PC it works
Flash > hub > Galaxy it does not?
Dont forget a PC USB kicks out 500mA of power which is about the minimum a flash drive would need. If the PC is not supplying the power to the USB via the Hub, I doubt the galaxy could supply that much.
Can you power the hub using the PC?
Yes, that's what I'm saying.
The hub works with the galaxy, but USB through the hub does not. I can connect a Keyboard and Mouse (Both with lots of lights on them) at the same time to the hub on the galaxy which SURELY takes more power than a single USB.
Everything works through the hub on the pc, and most things work through the hub on the galaxy but not flash drives.
So:
Keyboard + Mouse > Hub > Galaxy it works
Flash Drive > Hub > Galaxy doesn't work.
That's why I'm so confused. And power is going to the flash drive, the light turns on and flashes for a while, but is not picked up by the galaxy. The usb flash drive also works under normal circumstances directly through the OTG cable.
Human input devices take next to no power. A USB flash drive needs More. I believe this is your issue as previously mentioned

Seriously?
How come I can't just use one USB on the hub then... I'm only plugging one device into the hub, surely that should just be extending it? Or does it constantly try to power all of the ports? Is there any way I can debug the USB port on the galaxy? Or even limit power to just 2 out of 4 ports?
EDIT: I just read that a micro usb port is generally rated for 500mA+, which explains why the usb works normally, is it just the fact that all of the ports are powered?
MicroUsb is rated for 0.5A, that's correct.
However Usb-to-go is not rated for any output power, only for a list of compatible devices.
It may or may not work with other normal Usb-Devices, and could even be damaged if the slave device uses too much power.
(Unlikely with highend-devices such as the S3)
LED's take next to no power, the keyboard too.
Modern (=optical) mice got some electronic but it's not really high either.
Usb-Hubs however take quita a bit of power and flash drives do so too (especially when erasing "overwriting" blocks).
You could try a powerd usb hub , there might even exist some with a battery pack.
If not, it shouldn't be too hard to strap a battery pack to a hub, however that makes it heavier, clunkier and requires charging...

Okay, that makes sense then.
The hub is tiny and that's the idea, if I could get a tiny battery that'd okay, just irritating really. To be honest, I could do with just two ports, it is just that I sometimes want to use my flash drive in conjunction with another device or something and it's yet another inconvenience to buy another hub.
I may buy a charging pack for my phone, because honestly the battery life is abysmal, do you reckon that I could hook that battery pack up to the hub? Although I don't see that working because the hub in question has a dedicated power input.
Is there a set up you think might work? The idea is to be able to connect some extra storage and keep it fairly compact so that I'm not lugging a load of extra crap around. The hub I'm planning to use is a tiny square, probably about 1.5inches large.
I love the idea of my phone being a mini computer, it really does do just about everything I want, that would make it even better.
EDIT: I've tried a 2 way female splitter, no success there either. I think what I'd really need is a bluetooth keyboard that I can connect to my phone, that also has a usb port I can connect a mouse to, so I can then plug in my stick and use a mouse+keyboard combo.
Well, I have a Generic Gamepad which is being detected by my LWW but shows the "USB Power Consumption Error" as it requires 500 ma power..My LWW is on GB with stock ROM and kernel which supports OTG..So I saw a video that a 32 gb memory card had the same problem with Xperia S which was solved using a unpowered USB hub...So after buying that my Gamepad is detected and no error is shown but there's no power directed to my gamepad and it doesn't work. So does this mean that a powered usb hub will solve my problem?? Please help it's urgent. Thanks in advance..

The Dualshock 3 (PS3 controller) need also 500mA. Today I saw a post what the guy says the usb stick only work at a hub (non-powered), and recently I discovered that my controller can work on a powered or non-powered hub, but don't works directly. And I use a homemade OTG cable, but this broken, then I mod an adapter (usb to micro), I discovered with the cable only works with energy supply, with the adapter only need the hub with or without power.
My controller also is detected but only works if i hit the PS logo at center. I hope my info gives some tip.
I believe what the power supply can solve your problem since I read what other people make an external harddrive works only with powered hub. But in theory, your gamepad works without supply, but with a hub.
