USB OTG Help !!!

Today i bought a USB OTG cable.i am running full stock 4.0.4 . when i plug the USB OTG cable to my phone & then to my Mouse it does not work.all i see is my mouse led lights up for about 5 seconds then turns off.the same thing happens with my keyboard also.
My question is -
--> Do i have to make some settings changes ?
--> Install some kind of application ?
--> or is there something wrong with my OTG cable & i need to replace it ?

dude first install the usb modules on your phone...
go here http://forum.xda-developers.com/showthread.php?t=1588979

I installed the Modules but still nothing happens.it's the same.
Update : when i insert the USB cable of mouse half way then the mouse's LED lights up & stays but nothing happens the the mouse does not work.no cursor appears.
may b there is a prob with my OTG cable . i am thinking of changing it tomorrow.
thanks for the support.

did u install that app? did u install modules for stock kernel? did u try connecting pen drive?

yes i did all of those things . when i plug in the pen drive it's led lights up but in cell phone i don't get any indication of any new device found. . .

Stock ROM doesn't need any modules. I use Nokia N8's OTG cable, and it works fine. The mouse cursor comes immediately after connecting the mouse. The cable may be a faulty one or, it is for Samsung phones only, and since Samsung uses different wiring, so it is not working properly I guess..

[Q] A100 Broken screen trying to make mouse work!

Hey all,
I fell on top of my A100 a few weeks ago (Don't ask me how) and the side had a nice hit.
I noticed the screen is checked, but the image is clean and perfect.
The touch is not working anymore except for on 1 location, on the top part, a few square cm,
My problem is that I don't have any insurance left (took off the void) soooo,,,yeah...
I want to use it as a media player, attached to my LCD with HDMI, using a mouse to controll it.
Thing is, no mouse gets detected on this rom.
I tried to downgrade to Gingerbread from ICS, so I reset user data and cache, downloaded the ROM, changed to update.zip, placed it into the SD card, volume up + power booted it, and I get this droid opened up with a red ! on it...
Everything I try doesn't react
The mouse is a very simple HID logitech BT mouse with USB, connected to microUSB in the A100, I tried the G9x logitech too, but no luck.
Can anyone help me here? I can't use the screen at all, I am desperate
Thanks!

The USB port on the A100 does not have host mode, you can't use it for any USB devices, it is just a way to transfer data with a PC. If you can enable BT on theA100 you will get a mouse/keyboard working, I am just not sure how to do that with no touch response on the screen.

But I have seen multiple questions abut making host mouses work with USB on the A100, I'll try find the topics back
I could connect it by BT if I keep sinning the tablet around to make the few square cm work on the screen, but it wont be possible to accept
I tried using a screening app on windows, but sadly can only see immage from the tablet, no input remotely.

G2x-CM7 Nightly 11/25/12 Build, Trinity ELP Kernel

Broke screen. Need to retrieve internal sd.

So. My sister recently got a Verizon Galaxy S4 (i have no idea what model # or anything, as she lives on the other side of town) and she recently dropped it down some concrete stairs. She ended up breaking the screen (and possibly the digitizer) but the device still turns on. The blue light in the top left comes on, and the soft keys light up. Shes in desperate need of help because parts of her upcoming wedding plans (stored in pics, docs, and pdfs) are trapped inside this now half broken phone. She is unrooted, did not have USB debug enabled, and had a pin code on her phone. Is there any way i can adb in, or connect it to some program (win7) that would be able to pull all her internal sd card files and dump them on my computer? Any help is much appreciated.

So far i had 2 thoughts: have you tried plugging the device into Win7 and seeing if the regular mtp storage will work? Also if you had or could acquire an adapter to plug the phone into an hdmi tv, you might be able to send or upload the needed files somewhere, and/or enable usb debugging that way.
The pin lock might be a pain, but you could try guess-pressing the screen to unlock it. Otherwise you might be looking at also somehow using another adapter to plug in a usb keyboard.
I hope this gets the idea ball rolling anyway also you might be able to go into Download mode, even tho you can't see it, then flash a custom recovery where adb does work.

Plug it into a computer and take the files from the phone and add it to the computer.
If that doesn't work.
Buy an MHL HDMI adapter for our S4 from Ebay so you can connect to a television to see the screen there.
Hope it helps.

Locked Out

Hey guys, I'm new to XDA so please forgive the noob post, I'm just trying to get my phone working again. I broke the screen and now the bottom half of my phone is unresponsive (capacitive keys don't work). I'm rooted with TWRP installed, stock 4.1.2. Everything was fine until my friend thought it would be funny to put a lockscreen on my phone. I am unable to rotate my lockscreen to 270 degrees (how i've been managing to use my device with the help of gravity box on screen navigation keys) and am now permanently locked out of my decice. I can't input the correct pin that he told me (6735) or even incorrectly five times to reset via google account because the "ok" button is located on the part of the screen that I can't click. I thought that hopefully I had left USB debugging on so that I could send an ADB command to unlock my phone but it won't even recognize my device when it's plugged in, meaning I must have unchecked USB debugging. On top of that, my phone is in charge only mode, with the option to switch to USB mass storage stuck behind the lock screen. So my problem is that I want to go into twrp recovery, created a nandroid backup then factory reset my device. But of course, TWRP doesn't rotate either. I can click most of the buttons, including Backup, wipe, etc, but can't actually execute any action because the "swipe to ..." is located on the bottom of the screen - where I can't click. I was wondering if anyone could somehow flip the TWRP program upside down so that I could use it.
I just realized that I don't know how I would get the new version of recovery on my device anyway, because I can't even connect my phone to the computer for it to recognize as mass storage... any suggestions, help, advice, anything! would be very very appreciated. Thanks.
PS - This is MY phone, not stolen, not picked up anywhere, I know my google account info, I know the phone number, I know most everything about it so if you need some sort of verification that it's mine, let me know. I would just like to be able to use my phone again. Thanks

Your friend is a jerk. I'd punch him in the face.
Can you access the side load option in twrp?

I can get to the "swipe to start sideload" screen but can't swipe because it's below the crack... :/
Could I just get a new digitizer, would that fix it?

Would be easier to get digitizer+LCD already put together. I screwed up a new screen on my evo because the LCD didn't get heated up enough to separate the glue. I do have the official service manual for the phone so if u want I can send u what it says to do to separate the LCD and digitizer if u don't want to pay the extra

Any idea where I'd find it already put together?

I'll do some quick hunting, see if I can't find it

Or can select different parts on that listing, for example. Just search google for touch digitizer LCD assembly ls970, that's what I did. There are other cheaper ones but that one is just plug it in, screw it back together and go, so...

Hmm.....try fastboot, then load clockwork non-touch version through adb and see if that works.

I can't load anything through ADB because my phone won't connect to the computer - USB debugging is turned off. If I could use ADB I would just use an unlock command to remove the pin.
Thanks though.

That doesn't matter in fastboot. As long as you have the drivers for the o/s to read the device adb will pick it up. In windows 8 you have to install modified drivers for it to read it.

But if the devices supplies power to connected devices, there must be a way to get OTG fully working.
For example other phones without OTG dont supplie power. So there must be a solution

When I get home I'll solder an OTG cable with external power, I'll see what will happen (I'll solder it because I don't have a cable that offers external power) I thought the issue was data transfer, not power. Guess we will find out soon...
I'll update you all in a bit

I also remember an app that allowed OTG on non-supported device back in the KitKat days, I'll try and find the app and see what it does on android 7...
