OTG stopped working?! - Nexus 7 (2013) Q&A

Hi guys, I have this strange issue on my N7. I used regularly my OTG cable with USB devices or hard drive, with Nexus Media Importer, but it has suddenly stopped working! Nothing happens when I connect any USB device, it just won't mount.
I tried the "OTG Troubleshooter" app, and I have green checks on "USB Host Support" and "OTG Detected".. then if I connect a pendrive, nothing happens. No errors, nothing..
I've tried using the cable on my phone, and on another tablet, and it works properly.. is there something I can do??

Did you recently change ROMs or kernels? And have you tried using an app like Stickmount?

Nope, I've got the stock ROM.. I did recently a factory reset, since I had to ship the tablet to Asus for some issue I had (well, I still have it) with the screen, it won't auto-rotate sometimes. Anyway, they shipped it back to me and the OTG was working fine.. Until a week ago

[Q] Galaxy nexus USB data stopped working (still charges)

My Nexus is stock but it is unlocked.
I have the latest CWM on there (touch 5.8.0.2)
I was currently downloading all the necessary stuff to flash to AOKP but havent even got there yet because all of the sudden my USB isn't working.
I have tried two different cables, the stock one and a different one (both which were working before).
I get charging working through USB but no file transfer.
I just did a wipe data/factory reset and wipe cache via Recovery, and still nada.
Am I cooked here? B-stock with no warranty from Expansys, now currently kicking myself for not buying brand new.
[edit] yes MTP and USB Debug were/are both checked on
[edit2] a lot of my searches seem to indicate that you can move and transfer via adb in recovery or fastboot while having this error. I am not finding that to be the case.
[edit3] windows 7 does not show any indication of a usb drive or anything plugged in as it used to before. This is obviously making it hard for me to try things like reinstalling drivers and whatnot.
thanks
It probably has nothing to do with the USB port...
Plug your phone into your computer, and then scroll the status bar down. You should see a notification "Connected as xx" Select that, then make sure connect as MTP is checked, if it's connected via ptp (camera) it won't allow you to sync files, for what reason so ever...
If that doesn't help, then reflash stock ROM, that usually helps.. With most problems anyway...
If both of these don't work, then I'm sorry, but I can't help you. I'd then call Samsung, and send it in...

Yea MTP was already checked on. USB debugging being on would have auto kicked in as well.
I flashed AOKP but still the same issues. The hardware might have gotten bonked - I hate how fragile these tiny little ports are!
Is there some kind of diagnostic I can run to see if it is truly a hardware issue?
It's the kernel, try another one

Just swapped to Faux kernel... still persists.
I'm really starting to think its the hardware but crossing my fingers there's a fix.
the same thing is happening to me, it started yesterday too!
I am on AOKP b-23, Faux kernel....
plug in my usb, it can charge but absolutely nothing happens on the computer side, try it on number of computers too... but the phone is able to charge.

Mine started doing this. Would chargeā€š but sometime I couldn't transfer data or use adb. It seems that the USB didn't like to stay in my computer. Any little movement would unplug it just enough to keep it charging but nothing else.

I've since tested the MHL cable and also tried using the usb host cable to connect a mouse and both work... does that mean my data connection theoretically could be fine?
I'm using AOKP #23 with Trinity and not had this issue at all. Whether it's because I combine the ROM, Gapps and kernel before flashing I don't know but my phone is running fine
im having this problem as well. does anyone have a solution?
So all you guys that are having problems have enabled MTP through Settings >Storage?

Had this same issue yesterday ( phone was 1 day old ) had it plugged into my windows 7 machine and all of sudden the machine couldnt see it. So I wiggled the cable sure enough the computer saw it, jiggled it again and it would lose connection to the PC. Tried this on several PCs with Several cables and same result everytime. If I held the cable connected to the phone at the right angle it would never lose connection.
Ran to Verizon and the numbskull behind counter tried telling me that is normal and I would just have live with it, almost punched him in the throat. Demaded he go get another phone and show me if that one does it. It didnt so he swapped it and was to hasty about it, ended up giving me another cable charger and headphones WOOT WOOT
new phone doesnt do it as of this writing
See http://forum.xda-developers.com/showthread.php?t=1427539 This is probably the issue you guys are experiencing. Seems like you should swap it in or try to fix it yourself by changing the USB charging board.
settings/ storage/ menu button/ usb computer connection/ MTP make sure mtp is checked

i'm an android dev and this has happened to me. really really not good to no longer have adb access to my device. restarted both the phone and computer and tried a different coworker's computer and usb cable with no luck.
i used a samsung usb charger last night which i usually never do (i usually just charge it on the computer) and now this morning i have no data connection.
Hello,
have this problem already on my GNEX. After some reading, i got an idea to turn off Fast Charge in Trickster MOD.
And MTP now working .
Anyway there is an warning about fast charge - " Enabling this will disable access to phone storage" .
Problem solved
Yes, i can't connect mtp too and you rigth..usb fast charging is the problem.

Just so y'all know...Fast Charge is simply tricking your phone into thinking it's plugged into an AC outlet...rather than a USB port.
Thus MTP won't work.
same issue here
I'm having the same issue here. Charging works fine with 2 computers and multiple USB cables (as well as AC and car charger adapters), but data transfer has completely stopped working. My computer won't see my phone at all. I have the correct drivers (given that I used them to connect to my computer when I first rooted and unlocked the bootloader). Tried changing the drivers, but I can't get my phone to show up in Device Manager at all. MTP and USB Debugging are enabled.
The only thing I can think of is that I dropped my phone while it was connected, and now the USB cable only charges the phone if I bend it in a certain way (it usually requires upward pressure where the cable plugs into the phone to work). However, other USB charging cables work just fine without any pressure. Is there any chance that a new OEM Samsung USB cable might solve my problem? The other cables I've used weren't OEM.
I normally use a wi-fi data transfer app because the USB data transfer has been slow since day one, so that can be worked around. What IS a major problem for me is that I'm trying to re-root my phone after my root access was lost with the 4.0.4 OTA update. I didn't keep up with the news and only realized last week that my root access had been lost because I tried to do things that required root. Since the OTA update trashed my CWM recovery image, I seem to have no way to re-root and reinstall CWM aside from going back to my computer and doing what I did the first time. But if I can't connect to my computer, I can't do that. It also seems that I would need computer access to remove root in case I bring it back to Verizon for a replacement under warranty.
So on another note, if you guys know of a way to re-root my phone without connecting it to my PC, I'm all ears...

I have run into a lot of USB defects on the phones I have received. It might be wise to get Samsung to repair it, but you will be without a phone for a week. You could also try another cable.
I used to have similar issues except where the power got routed into the data port, frying my phone in multiple areas.
On Samsung's repair ticket they said REPLACED COMPONENT (I'm assuming this is the usb controller and port) this could be the solution but it requires sending it in.

USB Probz

I've had this phone for about 4 months and it was working perfectly, flashing ROMs left and right. Yesterday I tried connecting my Samsung USB cable into my laptop and tried to hop on that USB storage. What my laptop is telling me when I connect it is strange. It says that it doesn't recognize the USB device. I tried re-installing the drivers, shutting both phone and laptop down and restarting.. nothing seems to work. Please help me, because without being able to connect to the laptop, my phone is going to be boring and unflashable. Thanks!

I've had this happen before with my first sgs2, i'm on my third now. Try it on another PC, with another cable, if that doesn't work I'd just send the unit back for a replacement because the USB port is probably malfunctioning.

usb host problems

Hello, I have really odd problems with connecting devices to my sgs2. When I connect the cable my phone recognizes it and sometimes recognises also wireless mouse when I connect it. Problems starts when I want to connect pendrive or hard drive (with addictional power cable). The phone doesn't recognise it (already found that i need program to mount from market (doesn't work)) and hard drive shuts itself down after few moments.
Also when I take out cable from micro usb port my phone immidiatelly reboots sometimes it even does it when I just connect and disconnect cable without mouse etc on the second end. I am using rooted 4.0.3 XXLPW. Does anyone has similar problems or just my phone has something wrong with usb port? Looking forward for any helpful responses and sorry for my eng. Thanks.

OTG not working

So Ive run into a strange problem. I was watching a movie last night on my nexus, the file was on my usb drive connected via otg to the nexus. Today I try to do the same and I get no reaction from Stickmount when plugging in the drive. I have no problems charging or connecting the tablet to my PC, and the drive works fine both connecting to the PC and to my smartphone with stickmount as well. I also tried DLing an app called OTG Troubleshooter to see if that would help me. When connecting the drive it tells me that OTG is detected, but that "Mass storage USB device is not detected in linux/android". Does anyone know what the problem is?
Thanks in advance
Nexus Media Importer
I had a similar problem with the device not recognizing the OTG cable, it went away after I installed the Nexus Media Importer.

I tried with Nexus Media Importer as well, no success there either, it doesnt detect the drive. Thanks for the tip anyway
mine does the same thing with both stickmount and nexus media importer, I even tried 3 different OTG cables and flashdrives and get the same results

I have the same problem and have just tested that connecting a mouse or keyboard to the otg works without problems, what doesnt work is a flash drive. ( I have tried different flash drives to no success)
Does anyone know what the problem might be?

I uninstalled and then reinstalled it again and now it is working again. I think it might have been slow to update
Maybe you guys are using a Kernel with OTG+Charge option? if yes the problem maybe that you have to connect the AC charger and USB device together. If you don't need the OTG+charge you should deactivate that function.

PC does not recongnize the Tablet

since more than 6 months the PC or Laptop doesn't recognize the P605, I tried to change the microusb port, tried different USB ports, PCs with no luck.
When I'm connecting the tablet to PC the tablet will charge but nothing appear in the device manager, no detection at all.
appreciate your help guys solving it, I bought Tab S3 but I still like the old fellow more
No detection, so the thing's completely inert when plugged in?
When I plugged in my Note to my 3.0 USB laptop, out comes 'Device not recognised' in the taskbar, and that's it. However, it all works well when I plug it to a computer with USB 2.0 running XP/7. A brief search shows something about incompatible default/microsoft's driver with old(er) devices on USB 3.0.
As you've mentioned several attempts above including a hardware change, I believe the problem lies with software somewhere.
I have the same problem and get an "error 43" message. My Note 5 works fine when plugged in. I must have damaged the port upon changing the battery. I wanted to upgrade to 6.0 but looks like I'm out of luck....unless I can update via update.zip on my P600
