[Q] OTG Stopped Working. - Galaxy S II Q&A, Help & Troubleshooting

Hi, I'm having a problem with OTG, its not detecting anything ( usb flash drives, mouse, etc) after upgrading to official 4.0.3, it just says "USB connector connected" and doesn't pick anything attached to it.
Every thing was working great with previous ( ginger bread 2.3.4) version.
Any ideas how it fix it.
PS. Its a sim free I9100 and rooted.
Thanks

My USB Mount only works on Villainrom now..

Hey so I've been using Villainrom happily for a while now but recently tried out cyanogenmod which worked fine except for no USB mount. I figured it was just the rom and went back to Villainrom, USB working fine again.
With ICS themes being available to checkrom and batista roms, I gave them a go and found that USB Mount doesn't work on these either
I'm back on Villainrom 3.0 now after downloading PC drivers from google, samsung, and just about every source mentioned on XDA + search engines plus installing Kies and (almost considered going back to stock everything with Odin) no luck. The error message is USB Device malfunctioned in a big balloon message on the trey.
The phone will charge but not recognize a USB device being attached for mounting, tried turning debugging on and off, and starting USB from wifi.
Not a big deal as I can mount USB Now on VillainRom. But I'm super curious as to why none of the other roms are working for me
I have the original USB cable as well as another third party one. For some reason my laptop responds better to the third party one so I've always used that, tried both but no results.
Specs:
Windows 7 64 samsung laptop
Samsung Galaxy S2
Baseband: 19100XXKI1
Kernel: [email protected] #20
Build: VillainRom 3.0
Phone made in Korea, imported to New Zealand, currently operating in Korea
Any suggestions appreciated
XXKI1 is my baseband... could that be the problem?
Cool, if anyone comes here looking for help with Samsung MTP Device not working, uninstall ALL of your USB drivers and reboot. solved

OTG cable not working on a I9100G

Hi guys,
I'm in India and I have a Galaxy S II GT-I9100G (with a TI OMAP SoC) model phone. I've recently purchased a USB OTG cable from eBay for about Rs.360. However when I tested this cable with my phone, it doesn't even detect it. No message of any kind on the notification bar.
I tried the same cable with my friend's phone which is a Galaxy S II GT-I9100 (original model with Exynos SoC) and it worked absolutely fine.
Can anyone tell me what is missing in my phone that it is not working. Is this the case only with me or others having I9100G faced similar issues? If so, did any one find a solution for this. This is a very good feature to connect pendrives to the phone directly to copy files. But it is not working for me.
Any help would be very much appreciated.
Thanks,
Santhosh

Is the phone detectable by Kies? . have you updated firmware recently.Do a factory reset and try again.
Yes. i have recently updated from 2.3.4 to 2.3.6 via OTA updates and ever since my phone is not detected by Kies. also when i connect my phone to my laptop, phone's built-in storage drive is not accessible as well.
I've fixed the 2nd issue (accessing USB storage) by dialling *#7284# and using the PhoneUtil feature. But Kies will not detect my phone yet and the OTG cable is not being detected. i've bought the cable only recently after the updated to 2.3.6 and so no idea if it would have worked before the update.
One last question. when i do a factory reset all the data is lost. So if I take a backup of all the apps and data before the reset and then use the data to restore everything after the reset, will the OTG cable not being detected problem also come back after the restore ?
I got my OTG cable today from ebay.plugged in my usb drive and it was detected instantly but contents were inaccessible.It was due to ntfs file system.After formatting with FAT32 I could use it normally.

Are you in 2.3.4 or 2.3.6 ?
I'm going to do factory reset now and will post the result after I test it post the rest.

Hi Santhosh, go ahead with factory reset from privacy menu after backing up data.It will solve all your problems with Kies and OTG.Nothing to loss if you back up the data.Mine also suffered usb problem after the update.After factory reset everything worked normally.Hope this helps

Lucky you. Everything worked for you after the factory reset. There is no use in my case. Mass storage and Kies interface is working perfectly. However, USB OTG cable is still not working. I do not understand where is the problem.
I too have same I9100G with 2.3.6 version as you but why is the OTG cable not working in mine is what i can't understand.
Try another pendrive or usb mouse/keyboard.Ensure cable is inserted properly.Is it beacuse of PhoneUtil procedure?
Bingo. Factory reset actually worked. Thanks mate.
Yesterday after the reset I was connecting the cable and then the pen drive but it didn't work. Today I tried connecting the pen drive to the cable first and then to the phone and it worked. USB keyboard is also working. Hurray!!!

Try connecting the pendrive to the cable and then connect the cable to the phone. It doesn't work the other way.

So you proved the Galaxy S II is not compatible with USB On The Go
OTG function is absolute working on S2 i9100g
Hi all,
Don't worry if you are facing problem regarding the OTG cable not working on S2 G model because I have checked it. It is working very fine actually most of cheap type cable are not proper desingned that's why they are not working . Take the branded/Genuine S2 cable and see it.
I am using i9100G with my home made OTG cable the S2 G is very good phone.
A9 processor is up to the mark, Galaxy note has also A9 chip..............
Enjoy......................

USB Keyboards and Mice issue with SGSII USB OTG

hey guys
i recently got a USB otg cable for my S2(GT-I9100) and while this cable fine works with pen drives it doesn't work with any USB Keyboards or Mice that i plug into it. every time i do plug a keyboard or mouse, the phone completely freezes and i need to do a restart to get it running again
I tried applying the fix mentioned here (http://forum.xda-developers.com/showthread.php?t=1209567)
but still no good
any help will be appreciated
(PS: i am running siyah kernel 2.6.12 along with android 2.3.6)
Same here Bro
Heyho XDA,
sorry for pushing this old Thread,
but i have exactly the same Problem
Everytime i plug in a USB keyboard or a mice,
the Phone freezes instantly -.-
My Setup is:
CheckRom Revo v6
Siyah Kernel v2.6.13
Original Samsung OTG cable
Anyone else having this issue?
Or maybe a fix ?
Same problem
I've got the same problem. Pendrives, memorycardreader and systemcamera works great, but no mouse and keyboard.
Tested the same setup on my friends Galaxy Note and it worked out of the box. But not on my phone.
Download
USB Host Controller from the Play Store , see if that works.

It seems that USB Host and USB OTG are two different things. It has to be supported in the kernel. And I did root my phone and derooted by changing the kernel. I didn't save my original kernel so I had to download a new one. So maybe my kernel doesn't support OTG anymore.
I'm gonna look closer into this and report back it I'm getting it to work.

lost USB mounting CM9->Sammy ICS

Hey Folks.
Lost my USB mounting and I don't know why. Switched over from CM9 (mounting in windows works without any problems with the recommend driver) but now when I plugged in my cabel, windows can't installed the driver (using LP7 with CFroot).
I reinstalled the driver, choose manualy the driver but nothing worked.
Any ideas?
Thank you.
try with usb debugging mode...
must be your PC issue....put the cable to the direct mother board socket after PC reboot
Also tried it with USB Debugging on and off on every USB port and two diffrent pcs.
having the same problem since using ics r. remix and still cant fix

Nice to see that I am not the only one.
And yes to all others. We could use airdroid but I am not everytime in the same wlan.
aha well, some ICS roms dont support USB mass storage.. which is gay, but it should go back to normal when you flash back to a GB rom... which is wierd. I find many issues are fixed if... DUN DUN DUUUUUUUNNNN you unroot then reroot. This will delete all your shiz, so makesure you have a few CWM system backups saved
You probably know this, but i hope it helps

Could you list what LP7 rom you got (stock?).
Do you mean USB Mass Storage (ICS style) or MTP (GB style)?
I'm on WanamLite v10.7 (also LP7) with Siyah 3.0.1.
I didn't try stock LP7 / CF-Root so I'm not sure what might be the reason in that setup but here everything is working great.
You might want to try to download the latest Kies (even if you don't use it) and get the latest drivers that way - some times helps.
Hey.
Runing this rom:
http://forum.xda-developers.com/showthread.php?p=24753451&posted=1#post24753451
Which is nearly stock...deodexed and so on...
I am running atm the old LP7, now i saw that chainfire released the actual WLP7 (will flash it tonoght).
I mean the ICS mounting method. It is the stock one from this rom.
Kies is a good idea. Will also try it this evening.
Thanks for your help.
How to enable USB mass storage on Android 4.0 ICS Samsung Galaxy S2:

USB mass storage
Hi,
That doesn't seem to work with the latest updates of ICS (4.0.4?). When plugging in the HTC Desire, I get the USB notofication and tapping on that allows selection of mounting the USB mass storage. However, on my Galaxy S2, I don't get the USB notification and so no option to mount USB. Under settings -> More - I don't have any USB utilities.
I'm running CM9 nightly from Apr 13th and Siyah 3.1rc2 kernel. Anyone else?

known issue in the latest AOKP ICS...heard that you can access through MTP
access through mtp
Thanks for the hint about MTP and glad I'm not losing the plot re AKOP known problem....
I had seen the device show up and assumed it was MTP, but there is no indication on the phone that it is connected thru MTP. I didn't want to try anything in case I messed up. Not a pressing issue for the mo, though. I presume the BYT (bright young things) will work this out soon...

[Q] Need Help GT-I9300 Unable to Connect MTP/Kies after OTG use

Hi All
Greetings.
I recently purchased my SGS3. Everything worked fine initially, the phone would get detected to my PC and Kies would detect fine. Its later when I noticed the use of OTG cable has stopped getting my phone detected to the PC, nothing pops up when i connect to the PC, not even on the device (Camera Mode/etc. nothing pops up), it simply charges, even the PC does not seem to invite the phone.
Its my guess that after the use of the OTG cable, this has stopped working.
info :
Model - GTI9300
Android Version - 4.0.4
Baseband version - I9300XXLFB
Build Number - IMM76D.i9300XXBLFB
Thanks!
