I have a completely stock, locked and unrooted Nexus 7 2013, and whenever I plug it into my computer, it will not recognize my device.
I've tried:
- checking/unchecking MTP
- switching to PTP
- turning on/off USB debugging
- uninstalling and reinstalling drivers
- Nexus 7 toolkit to install drivers, wouldn't work
- Wugfresh's toolkit, and followed the driver guide, still nothing.
After uninstalling the driver, Windows would allow me to choose a driver to install, but it would always end up saying "Windows has determined the best driver is currently installed" or something similar to that.
I am updated to the latest build, JSS15R. Before I updated, my computer was able to recognize my device just fine.
Is anyone else in the same situation as I am?
Hmmmm, are you using a USB extender cable or a long cable. Mine fails to pick mine up after the JSS15R update unless I use the given micro USB cable.

I'm using the cable that came with Nexus 7 that says "ASUS" on it.
When I tried to root my device I had a lot of problems connecting it with my PCs/Notebook.
I tried WinXP, 7 and 8 and got crazy because I never reached a reliable state.
If I remember correctly WugFresh's toolkit has an utility integrated that lists all "Android USB devices". I had to remove them all before it finally worked - and in the end I had to repeat this twice before my Nexus was rooted and had a recovery. And even then I had to dis- and reenable MTP etc. a few times.
After this I had to reinstall different drivers so that it was recognized as MTP again.
Took me one day for a process I expected only an hour.
So try the Root Toolkit and the utility inside.
I tried that. I might have to give it a try again. I might have missed some devices.

I've recently run into a problem with my phone being recognized by my computer... basically it just doesn't work anymore. This happened after upgrading from Midnight ROM 5.3 to ACS Frozen 1.2. At this point, when I plug my phone into the computer, it only charges and does not enter into usb connected mode. On the computer I get a pop-up message saying that the USB Device is not recognized. After searching through these forums and others, I have tried uninstalling / reinstalling drivers, installing PDANet, switching USB ports, and Switching USB cables... All multiple times. The best I've gotten out of the process is immediately after certain tries, I am able to get the usb mode activated, but only once. When I try to boot the phone into download mode because I'm trying to upgrade to EF02, it is no longer recognized, and then when I do a regular boot, it is still no longer recognized.
Any help would be appreciated.
Thanks,
Greg
I've also toggled USB debugging multiple times...
Which OS is your PC running?

Try downloading the android sdk and updating all its files and repo's? I had to do that for my w7 x64 pc to see my epic
Posted by some phone named the Epic.
Your drivers crapped out or your cable is flaky. Try a different cable. Also turn on USB debugging and go into Device Manager in system in control panel. Go to the unknown USB device (may say Samsung Android) and hit update driver and let it search Windows update for drivers, will take a long time for all the drivers. Then reboot and should work.
Are you using the cable that came with your phone? Mine stopped working and I had to buy a new cord off amazon.

Win 7 x64 is the OS...
I've found a temporary workaround by pulling the battery, plugging the device into the usb, starting it into download mode, and then replacing the battery, but thats not really practical for storage purposes, only for the one time install of EF02. I have used 4 different cables and reinstalled the drivers multiple times. I am going to try reinstalling the sdk and see if that helps, as well as searching drivers using Win 7 Device Manager.

Hi All, I've got a USB connection problem with my Galaxy Nexus. When I connect it to a computer, it will start charging, but doesn't show that it's connected to a computer and the computer doesn't show that a device is connected. I've tried on a few different Windows machines and don't get any change in the device manager. There is no "unknown device" nor device with an error. I've been searching the Internet and this forum, but still can't find the problem after a couple of days. Here's some details and things I've done:
I did not install the "force fast charge" kernel mod.
I've tried a couple different cables and verified that the cables worked with my wife's Galaxy II.
I've tried several different computers.
I've tried MTP and PTP storage options.
I rebooted everything several times.
I drank heavily.
I tried a factory reset.
I updated Windows Media Player to get the latest MTP software.
I installed drivers packages even though it never gets to the point of installing drivers.
Does anyone have any other ideas before I smash this thing with a hammer?
Does anyone have any ideas? At this point, I'm thinking there is a hardware problem.
Go into Menu -> System Settings -> Developer Options -> Turn on USB Debugging.
Not a guarantee, but something to rule out.
I've got USB Debuging on. Thanks for the reply.
Can anyone help? I'm having the same exact problem. My phone charge but is not detected by my computer. I am having this problem right after flashing AOKP ROM B35. This is very important, one mistake and my phone will be bricked as a computer to phone is so important !! There is nothing detected at all under device manager. Tried it on several laptop to make sure it isn't just my computer.
someone?
Uninstall the drivers you have for the s2. Reboot and install the official drivers for the galaxy nexus. Reboot. Then try.
If that doesn't work... let the phone load a while and just keep trying other ports on the computer. I saw this with my other gnex that it would take a while to realize a USB to be connected. Also make sure the USB is in completely... don't jam it in but make sure you know its All the way in. ( no pun intended) What's funny is my gnex will detect it instantly... but the other one takes a few tries.

Thank you dude. It doesn't work. Prior to installing this rom, my nexus is detected instantly. There is something wrong with the process i root or something. Now i can't do anything as It is not detected by my computer. Someone please help.
Indeed is the rom that is causing the problem. I opened NEXUS toolkit and rebooted my phone into boot image. It will sense it and i can operate from there. I've restored to factory and now my phone is being detected. I hope the thread starter gained something out of it too
I've never had a problem with android file transfer up till I rooted today. My wife has a stock Nexus 7 and I can plug her Nexus into my computer and the file transfer app will start. I have usb debugging turned on and the usb connection on my tablet is set to Media device.
Now as I'm typing this my Nexus has been connect to my mac for about an hour. I just went to the USB settings to make sure I had Media device selected and the file transfer window popped up out of nowhere. I killed it and tried again and it won't come up. Maybe in an hour or so if it does the same thing.
Any ideas as to what's going on? Very strange behavior.
Disable USB debugging.
Unplug/plug in your nexus.
The USB IDs change for some reason when you have USB debugging turned on and the MTP device isn't recognized as such. PTP (camera) mode continues to work for both cases though.
Thanks for the suggestion but It still fails. I disabled debugging and still can't connect. Switching USB modes didn't help either.
If that doesn't work uninstall the adb driver & then plug your tablet back in so it will reinstall
My next suggestion would to reboot the tablet with USB debugging turned off.
If that doesn't work, my next suggestion would be to delete the existing drivers and force reinstall.
All with USB debugging turned off.

Make sure after you plug in your device you're looking at your tab and click OK on the pop up........

Thanks for all the suggestions. It's working now. I was just about ready to delete the driver and the tablet started to be recognized consistently. I was in the settings screen and toggled debugging on and off while plugging in the tablet. I noticed the info bar at the top alternating between showing "debugging" and "media device" and I selected each one a couple of times when they came up. I think that it finally worked through the ID confusion that was mentions. I'll follow the the rest of the instructions if the problem comes back.
Thanks again.
It's acting up again so I'm going to try deleting the drivers. I thought I knew what to do but I can't find any information. What's the procedure to delete the driver? I'm running os x lion
I've tried every suggestion in all of these threads so far & nothing worked. Even after I deleted the ADB drivers, windows 7 would automatically reinstall them. When I tried to update the drivers, win7 said they already had the best drivers (ADB).
Here's what worked for me:
I had to turn off USB debugging, delete the ADB drivers in Device Manager, then reboot the device while it's still plugged in. Windows recognized the device as an MTP device & installed the drivers before it even fully booted.
I'm not sure how I finally resolved the problem on my mac. I toggled debugging on and off and rebooted a couple of times. That may have done it. I also ran the adb script in the SDK platform-tools folder. I don't know what that script does exactly but possibly it reinitialized the driver and ID.
Anyway, hopefully these workflows will work for others.

Rooted my nexus 7 (2012) last night and struggling with my laptop not recognizing it. This thread solved it!
Delete the ADB on my window, toggle off debugging and restart the nexus 7 with usb connected to laptop. works like a charm.
Thank you!
Guys, my N4 got this problem too.. until just a few minute ago
I read somewhere ini goge groups (i think N5 group), and found explanation that we can change ADB or MTP "mode" on device manager. On "Androoid ADB Device" right click and select "Update Driver Software". Click "Browse My Computer for Driver Software" and then "Let me pick from blablabla...." And then select MTP USB Device, "next" and my N4 detected on Windows Explorer.
Hope it will be usefull for you guys.
Hey guys. I been here for like 4 hours just dabbling with everything. And cannot seem to find any solution to this...
I have uninstall all drivers and restarted like ten times now doing the same process over and over, cleaning up each file carefully of the nexus or any android device.
My problem is when i plug in my nexus 7 2nd gen, it seems to not even detect squat.
I have usb debug enabled
my MTP is on
( if i switch to PTP i can access the folder)
Ive done fresh start on everything i even look through device and try changing the option to MTP and STILL DOES not work
I don't even see my nexus 7 in my HDD external or anything, nothing pops up but an ADB success driver, and when i changed it to MTP a MTP success driver with STILL no luck....
I just bought it today and it worked fine earlier, now when i root it and stuff it seems to be glitchy with my MTP
I even factory reset everything i couldn't access my ADB
any help would be appreciated
Someone said that manually updating the adb usb driver in devices should show you a choice, choose mtp. It should then sort itself out properly.

On your Nexus, open "settings", click on "Storage", click on options(3 vertical dots on the top right corner), click on "USB PC Connection", now check MTP option.
Try connecting to your PC (or Mac) now. I didn't have to do that on a stock build, but for some reason I had to do it on a couple of custom roms. Hope it helps ya out...
Try enabling USB debugging. I know it sounds odd but its helped me with my devices.

do this only if you can see PTP on PC
On PC check device manger, on Android if there is ADB driver - uninstall it
On N7 set to MTP, debug off and reboot with N7 USB cable connected to PC
It should re-install the ABD drivers on PC before N7 fully boots up
You will be back in action.

Actually for me, it's the opposite. If usb debugging is on I can't access the device to view files. Try disabling it?
yea thanks though everyone I got it to work. I had my old nexus and new drivers mixing up my ports for some reason not being able to access it at all
Ok so I have a rooted nexus 7 that won't show up as an mtp device ever since I rooted another nexus 7 on the same computer. I have uninstalled all the drivers and re installed them a million times with device manager and USBDview nothing works. It connects to other computers as an mtp device, however ever since I rooted the other nexus 7 on the same computer it won't work. Also I don't have access to the other nexus because it was my friends. Obviously it's a computer issue because it connects to other computers as an mtp. I'm really out of things to try as I have searched for this problem, but only found people saying to re install the drivers. I would really appreciate some help because I don't know what to do. Thanks.

I also have weird issues. What I usually do is make sure the Nexus is configured for only one connection. So for MTP mounting I have PTP unchecked and USB debugging unchecked. Then I plug into the computer.
If it doesn't mount as MTP, I find it's usually because Windows has attempted to connect via ADB drivers. So I go into Device Manager and uninstall the device under "Android" while checking the box to remove drivers for the device. Then I unplug the Nexus and plug it back in, and it uses MTP drivers. I've always struggle with these driver issues for the Nexus, i don't know why it's so difficult. Good luck!
When I had issues with my mtp I had to uninstall adb drivers then plug my device back in so it would use mass storage and install the drivers. Somehow I have adb and mass storage working now with USB debugging on.
Check in device manager when you have adb uninstalled and see what your device comes up as.

I uninstall the adb drivers but for some reason windows automatically installs them right back instead of mtp drivers and then if I go to update drivers and select mtp as an option it says it won't work
When I try to install the mtp drivers it says "Windows found driver software for your device but encountered an error while trying to install it...your device can't start" Then it automatically installs the adb drivers. What would be the reason it won't let me install the mtp usb drivers? Has anyone else encountered this?
