1-try swap the pendrive for a mouse or a keyboard and tell us the result.
2-try swap the otg adapter.
3-if none of these worked plug and unplug some times and send us a logcat
i dont have an otg cable to check with mouse/keyboard as im using OTG Pendrive.
attaching the logcat

the "otg pendrive " that u are using is something like this , im asking cause its the first time im seeing one :umb::
I think your logcat is not properly good, it as only one line, should have much more code, i think something went wrong.
and i also think that your problem is somehow related to kitkat imersive mode bug
do you use any specific app for the otg pendrive?
if you have imersive mode enabled try disable it.
I guess there z no option to disable immersive mode.im on stock unrooted.

Attaching any USB peripheral requires the device to have USB On-The-Go (OTG) support. A lot of the newer (and high-end) devices have this, but yours does not. So it's not possible. It's not just a simple software mod. USB OTG requires the device to have a USB port that's capable of delivering power output to power low power USB peripherals like keyboards, mice, flash drives. For that same reason, in the video it is mentioned that only low power webcams work. It's at the hardware level, so no it won't be possible with your phone at all.

Yes you're right, your device does indeed have full OTG support. Sony never mentioned it in the official specifications, but I did a search in your device's forum and found info about it. In that case, I guess the procedure to getting the webcam to work is more hardware specific, so can't say whether it can or cannot work with your device. Your best bet is to ask a dev for your device about it, and see if they're interested to look into it. Also, the guy in the video said only low power webcams work. This is because the USB port can't deliver that much power output.
Having USB Host mode and even a powered USB hub is not enough to use a USB webcam.
You need kernel support and a custom app that accesses video4linux interface (/dev/videoX) OR a patched android framework that routes video4linux interface to android's standard camera API.
In other words, you must be able to modify and compile your own kernel and custom ROM for your particular device.

You can't just edit the boot.img, you have to edit the source and then compile it. Either learn how to program etc. Or ask a developer for your device to have a look.

I have a Sony Ericsson Xperia Neo V running Lupus kernel and FXP152 (CM10) ROM. My phone's specification says it supports USB OTG. How can I get this feature?
Also, I am unable to use USB Mass storage mode. Its disabled for some reason. Can anyone explain?

hi dear
for your broblem
first of all you must buy a cable that mach your phone port
second your phone must be unlock and root
third you must use modules that is with kernel (flash with CMW) and then install ModuleLoader.apk and select the modules you installed
then you must install a app (like stickmount.apk) to mount the usb you attached
you can found apps in apknew site
may this help you

hello dear
I sow that page but I've no idea why you cant see the drive in your computer
first of all you must ENABLE your USB debuging from your device
and make sure you have installed your phones driver in your computer
maybe your phone is in MTA mode so you can see your drive under your phones name in camputer
and make sure your cable is working fine.
may this helpfull

Yes, I had enable mass_storage in buil.prop file before flashing that zip. Actually it used to work in FXP 148. But now am on FXp 152 ROm, and now that patch is not working.
I have USB device drivers for my phone from some other path. But thats not getting identified by driver update.
Currently, my phone gets identified in MTP mode in Device Manger, but no drivers installed (shows as yellow question mark).
Hy everyone!
I have problem with my samsung galaxy tab P7500..it wont recognize my usb. in notification bar shows that is connected but it is not. there is no folder od something with my usb staff. it worked fine, and then just stopped. i dont know why
before, when i connected usb, tab opened a folder of usb, but now nothing..
did i miss something? where did i get wrong??
please heelp!!
P.S. sorry for my english
Switch to a different USB port. It seems like a stupid answer, but it is a common problem. Switching from the form factor USB ports (front panel) to the board mounted ports (rear panel) or visa-verse often works.
i know this may be an old post but here goes, i have the same problem, my PC tells me that the drivers for my tab are installed but i can not see it in my PC.
i connected it to different USB ports but still i can not see it.
i tried turning the debugging on/off still to no successes.

Try unistalling kies and the Samsung drivers, restart the pc and just install the driver. See if that works.

Okay, I just googled your problem... Try removing the device from device management (sorry, it was a Dutch site, translation might be different) in Windows. Then reconnect it.

Then I only have 2 more options available before I run out of ideas.
1) did you enable mtp under the storage options on your tab?
2) your USB cable might be defective. Try a different cable.

Hi
Hope somebody could help me.
my tab is p7500. official ics and rooted. i try to connect usb otg and it working by showing "USB connector connect" .
I can connect it with 1gb flash drive. But when i connect with 2 gb flash drive or higher, the tab will show "High-power usb device connected. cannot access to this device".
why it show like that? is the tab only can access flash drive with 1gb memory and below? or there is some setting that need to be done if want to connect with higher than 1gb flash drive?
Please see the picture attach...

I can't believe that the p7500 wouldn't support flash memory over 1gb. I've heard of people using a USB hub that has it's own power supply for OTG.

I like to just share a PC drive or folder on my network, then us ES File Explorer to find the video on your network and stream it over wifi to MX player on the droid. It's a little technical to set up, but a good thing to know.
Hello,
I've used my tablet with flash drives etc. with the OTG cable. Before few days the OTG stopped working.
I though it's from ES File Manager because I use this app very often and I have clicked somewhere and disabled the OTG function.
So, I made decision to pre-install my android firmware and clear everything. > I did this.
And then I put the OTG cable with the flash drive connected and then a USB mouse - the flash drive does not connect, the optic ot the mouse only lights up and then it goes off and the mouse does not work too. I tried the OTG cable on my phone (SGS 2) and it's working perfectly.
Can you guys help me to solve this problem?
I am trying to use my flash drive with otg cable. I connected my atrix with a USB hub, powered it and also connected another pen drive to it but there was no notification.
Is otg not working in kitkat 4.4.4?? Didn't try in 4.2 or previous version.

OTG is probably not going to work at this time. It is important to keep in mind that Z is working on stability and things along those lines. OTG is not something needed to have stability.
Try using the "USB host controller" app.
Is OTG support releated to hardware or software, kn other words can OTG be enabled with only adding that feature to kernel or I need some hardware requirements beside usb flash and otg cable?

OTG support requires both hardware and software support. If your android is rooted then you can enable OTG support using USB OTG helper
You require OTG cable when enabling OTG support.

No you cant.
First lets understand how otg works.
First of all , for Pendrive or Storage to work , you need power for it to function.
There are two eays to power up the pendrive.
i)Power from your phone's battery
ii)External Power
No matter how much you tweak your software , without providing power to the pendrive , you cannot run an otg.
You can always google and find out if your chipset supports otg or not.
If your chipset supports otg and your device doesnt , you can always root your device and try StickMount or USB Otg Helper , but if your chipset doesnt support otg , you need to power up pendrive externally , using a usb Y cable.
After you've acquired the cable you may try the above mentioned root applications to try out your luck.
I am 90% sure that your device wont support otg even after providing external power because of your kernel.
Your kernel is the one which controls all mounting point and hardware devices in your phone.
Good luck/

So, if I understood it, if my device doesn't support OTG by hardware, I still can make it work using Y cable, and if it still doesn't work than I need to add kernel support?

Its worth giving a try , usb y cable is available for less than $5 now a days.
For mounting ntfs , USB Otg Helper is mandatory though , even after kernel modifications.
Or maybe libraries can be manually installed
Anyway , Cheers

I needed a tab for my car dash entertainment/navigation so i ended up buying a cheap verizon ellipsis 8 (model QTAQZ3). Its perfect for runing multimedia and navigation but it dnt have Otg support which i need to attach rear view cam. I rooted it with kingroot 4.1 and installed root explorer. I have placed android.hardware.usb.host.xml and updated vx.core.hardwarwe.xml. now now i used all otg diagnotics and mounting apps but all are showing otg and usb host active but Linux kernel 3.10.0 (andoid 4.2.2) is not otg supported and no usb flash or usb cam is geting recognized by ellipsis 8. Is there any patch for kernal that will do the job? Wht should be next step??
