OTG not working - Nexus 7 (2013) Q&A

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

mine usually recognizes the cable, it is the thumb drive attached to it that it usually dosent see

im no expert but i was having issues with a physical keyboard through otg
on stock rom it times out
im on cm12 may 30 2015 with elementalx kernel
after flashing i plugged in the otg with the wireless keyboard reciever
nothing. worse than stock.
i downloaded all the usb otg helpers etc what not
in conclusion
i somehow managed to get
s3c usb host drivers for android
installed them from some site that i cant remember anymore -- really dumb --. seemed sketchy but had nothing to lose
altought now i can type still getting the same crap problmes i had with stock but not as bad. time s out

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.

How do I mount a USB drive?

I've got 4.0.2 running - mice work fine. But how do I reliably mount USB drives? I tried downloading USB watcher OTG from the market, but the application is incredibly buggy and unstable.
Any other ways?
Thanks.
ICS and the Galaxy nexus no longer uses USB mount.
We now have something called MTP, and If you have the correct drivers installed your device should appear in my computer as a media device and then you just copy and paste as normal.
I have just had a ***** of a time getting my GN to show up in My Computer. In the end all I had to do was update Windows Media Player.

Lots of people seem to be getting these confused. I'm talking about using USB OTG to plug USB flash drives into the Nexus and then access the files on the drive.
MTP is working fine for me with both Windows 7 and Windows 8. No need for installation of drivers, it seems to be 'plug and play'.
Thanks for the reply!

ahh, got ya. I've had MTP on the brain since i couldnt get it working last night. I got it working just before i read your post
Mount command via something like terminal emulator? .. Not sure on the full details but it should be something similar, maybe?
Also I see you've jumped ship as well cjward ;-).
What a coincidence. Literally as soon as I posted this, Chainfire released StickMount, which allows automatic mounting of USB sticks in the Galaxy Nexus. For anyone else wondering, head over to the thread here:

are you running stock kernel or custom kernel.
i think unless you run a custom kernel, you will not be able to mount a USB drive.

I'm having a harder time finding an adapter that turns USB into micro. I ordered what I thought was the right product but when it arrived it's just to convert someother weird mini USB to standard micro. Anyone know the best place to get these? Preferably in the UK?

OTG through a HUB

Hey! So i managed my S2 to work with an OTG adapter. Now it recognizes Flash drives, USB mouse and keyboard as well. My problem is though, that i'd want to use both the mouse and the keyboard simultaneously, and later on my tablet as well.
I've got a USB hub which was pretty cheap i guess,
ht tp://itmedia.sk/item-images/other-usb_omega_hub4portSTARpowercapable/it6818_2.jpeg?nc=032
When i connect it to the OTG adapter it lights up, and if there's a flash drive attached to it when i plug it in, the phone recognizes the flashdrive without problem. As soon as i plug in a second flash drive, the light goes off from the HUB and both of the sticks get unrecognized. Also, the mouse nor the keyboard works through the HUB somehow..
I need to buy a specific hub with OTG support or a power hub perhaps? Could anyone help in this? I looked over google and stuff but people seemed to say different stuff at almost every site.. Thanks!!

Oh well that's quite interesting. Then you're saying this piece of video could be fake perhaps?
Since i can post links yet, search for this on youtube: USB HUB Support On GALAXY S2
Check the very first video.
I'm convinced that the every phone can handle only one device connected at the same time.

Well, it surely doesn't seem that way, that's why i was asking, since it's possible.
Weird.... i got sgs2 and 4-port usb hub and when i connect 2 pendrives to hub and hub to phone everything works good (i see UsbDriveA and UsbDriveB). If your hub have dc input you can try connecting power supply to this hub. Maybe this hub isn't compatibile with your phone.

OTG stopped working?!

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

I have the same problem
Sent from my SM-T705 using XDA Free mobile app
Works fine for me on my 10.5, maybe you have the wrong otg cable?
Do you see the notification in the status bar when connecting a device.
no notification, but with same cable and same USB pen connected to Samsung S6 it works
not sure why and how it worked but connecting tablet to PC, it was recognized as external storage on mac with android app

I am having same problems as others. Tried al404's suggestion in various forms and still nothing. The problem may be unique to the Wifi only models. Does al404 have LTE? I also have loaded various ROMs, including Liquidsmooth (which supposedly had OTG control), and they have not helped.

Phone isn't recognised by computer nor is my USB C stick

Hello,
I hope someone can help. I am trying to get my computer to recognise my phone. I am not rooted and I have Marshmellow 6.0.1
I unlocked developer options. I bought a cable and it worked! The computer saw my phone. However it stopped seeing my phone. Why I don't know! But when it did work I saw the driver was not for the 5x but from my S4. Well since it's not working I ordered the recommended USB cables by Benson Leung Tech Matte. Still unable to see my phone. Tried cables on another computer with same results. The computer I tried it on recognised my phone and then it also stopped seeing my phone.
I also bought a usb c stick to use on my phone. My phone responds to the stick but when I choose for MTP from charging nothing happens and i cannot access the USB Stick. In Dev options MTP is selected. I also noticed that USB tethering is not available. I have no clue what to try next.

USB debugging needs to be selected. Also, you need to toggle to PTP and back to MTP

Thanks for the drivers. USB Debugging is on. When I toggled Charging popped up instead of PTP and so I kept toggling and it finally went to PTP and so I toggled MTP and it goes back to charging! So I kept at it until it finally went to MTP. Is this normal? I counted 12 tries before changing from charging to PTP! But the computer doesn't see the phone. I did it a few times

i honestly never thought about this, is this even supposed to work without some kind of an OTG adapter. i mean sure, the plugs fit, put do the pins match/work for that configuration?
from how you describe that your phone reacts i would guess it doesn't, and it sounds more like your phone goes into client, as opposed to host mode.
very interested to see what someone with more knowledge of the matter would have to say about plugging a usb-c memory stick directly into your phone.

I can read/write to a sandisk USB memory stick using the proper adapter and using USB OTG file manager for Nexus from the play store.

I've used several phones on my PC and at first it had a little trouble but finally settled in. Kind of like a new ROM. You have to give it a while to settle in and get its groove on.

not really a surprise there, but what OP described was putting a usb-C stick directly into the phone, without any cables or adapters in between, with the question emerging if that is even supposed to work (which in his case didn't) due to possible problems of the pin-layout, etc.

that does not explain his PC suddenly not recognizing his phone anymore though.
at this point it sounds to me like either there still is a driver issue (e.g. the mentioned S4 driver wan't properly uninstalled), or one of the usb ports (phone or pc) has an issue.
try different ports on your PC and make sure other devices work with the ports. if not try if you can get it to work by applying a little pressure in different directions to the cable and listen out for windows' annoying usb sound.
on the other end make sure your phone really is connected correctly to the cable. it should snap in just like the OEM charging cable which took some time getting used to to overcome the resistence of the usb-c port.

Thanks again for your quick reply,
I tried my Samsung Tab II tablet and my old S4 on my PC and they both work as advertised. Recognised right away and I hadn't used my tablet to my PC before. What I think is maybe its the USB on the phone itself?

I think its the phone itself, since it did work briefly. Also with the USB C thumb drive the phone recognises it but will not read the thumb drive. I ordered it from play store I wonder how getting it repaired/looked at is going work Have to wait until Monday to call!
Hello again,
I Hope you guys like some feedback about my issue. Contacted Google and they asked me just about all the same questions and had me do some screen shots and try some of their ideas such as factory reset, trying other computers and other cables. Nothing worked so they sent me a new phone! Just got it yesterday. Would have been here sooner but I was busy!
So got new phone setup and the computer recognizes my phone on PTP but not MTP. Also my driver for the phone is a generic nexus and the it still shows up as a samsung! How can I get the new driver if when i do a search for new driver my computer says I have the best driver already installed? I don't want the driver to still be a problem. So i hope you guys have some answers. Lol! I know you guys do!!

If you had a samsung phone before you need to uninstall all the samsung drivers then install the proper nexus drivers
I was a little worried about uninstalling the driver but it worked!! Thanks! Now i can root it!!
