Hey I found a solution to this via mkh at https://groups.google.com/forum/?fromgroups=#!topic/android-developers/0-RzE0v-G3k

Try this (as quoted from the above source)

When the Nexus 7 is plugged in there is a persistent notification that indicates "CONNECT AS / Media Device (MTP)". In this state adb devices will not show the Nexus. Not exactly obvious why, but I you select the second option "Camera (PTP)" the device is available for debugging. This choice is persistent, and I'm guessing that with a band new device it will connect as MTP until told otherwise

An important note about Nexus 7: There is no option for USB debugging readily available in the device Settings for 4.2.

"Open Settings, then go to phone details (where u can see kernel, Android-version etc) then just tap your Build number 'JOP40C' 7 times!"

This sounds ludicrous, but after I did this, the developer options unlocked and I was able to see my nexus 7 in Eclipse (mac, Mountain Lion) for debugging.

In my case when I got an empty list using "adb devices" I found that the device manager showed the Nexus 7 tablet under 'other devices' with that dreaded yellow exclamation point indicating that the driver was not installed correctly. Why Windows recognized part of the tablet file system, I don't know. In any case I manually updated the driver to the google usb driver in android-sdks\extras\google.

Then adb gave me the following:

C:\Users\Brian\android-sdks\platform-tools>adb devices

List of devices attached

015d25785b601611 device

instead of a blank. I hope this doesn't mess anything else up but I can now talk to the device.

Had the same issue, Windows 7 32-bit; visited the site that Graham linked in his answer but wasn't happy running PTP (though it did work). Following the steps on another post belonging to the same thread sorted it (I can now connect as MTP); again, a direct quote from https://groups.google.com/forum/?fromgroups=#!topic/android-developers/0-RzE0v-G3k (thanks sfoucher!):

  1. uninstall the driver in the device manager with option "delete the driver software for this device"
  2. reconnect the Nexus tablet
  3. let windows install a default driver which will be inadequate
  4. uninstall again the device in the device manager with the option "delete the driver software for this device"
  5. let windows try to find the driver, this process will fail
  6. go back to the device manager and right click the failed device and update driver
  7. choose the driver location in the android sdk directory (android/extra/google/usb_driver)

I should add that after step 5 I had Nexus 7 listed under Portable devices looking OK but had another Nexus 7 entry under Other Devices to which I applied the driver. My Nexus 7 now appears OK in ADB and Eclipse. In device manager I have Nexus 7 under Portable Devices and Android Composite ADB Interface under Android Device.

I too had the same issue on windows 7 64 bit.

Following thing solved my problem.

  1. Connect the Nexus 7 and tap on Settings-About Tablet-Build version 7 times.!
  2. This will install basic driver for windows
  3. Now, tap on connected as media device(MTP) icon, but you will need to change it as Camera device then
  4. Go to device manager on windows, select Nexus 7 and then update the drivers using the driver avaliable on this link http://developer.android.com/sdk/win-usb.html - This will install a driver ( You can use it with this one)
  5. Now tap on Connected as Camera device and change it to media device - This will install one more driver and you are ready to go.!

i was having the same problem and my solution was to download the device driver from Asus. Below is the link.

http://support.asus.com/Download.aspx?SLanguage=en&m=Nexus+7&p=28&s=2

This link was not referenced yet in answers and this is the best one I found:

http://www.theandroidsoul.com/nexus-7-2013-drivers-installation-guide/

That's how I solved this issue with a different device.

  • Download the drivers, unzip in a folder https://developer.android.com/sdk/win-usb.html#top
  • With your tablet plugged, go to System -> Device admin -> Android Device -> Properties -> Details -> Hardware ID
  • You'll find something like USB/VID_XXXX&PID_YYYY, we will need those XXXX and YYYY later.
  • Go to the folder you put your drivers and edit the file android_winusb.inf manually.
  • Add this:

    ;MY PHONE
    %SingleBootLoaderInterface% = USB_Install, USB\VID_XXXX&PID_YYYY
    %CompositeAdbInterface% = USB_Install, USB\VID_XXXX&PID_YYYY&MI_01

  • Save the file

  • Go back to device manager and try to update the driver with this one. (Driver -> Update driver -> Search in my computer -> Choose from a list -> Use disk).

That worked for me on a Quechua Phone.

What worked for me is downloading the USB driver from the ASUS website:

http://support.asus.com/Download.aspx?SLanguage=en&m=Nexus+7&p=28&s=2

(you have to select the OS, which sometimes doesn't work, e.g. on the link Google returns when searching for "nexus 7 driver"). In that case, click on "Drivers and Download" and search for "Nexus 7". That gets me a page with a working OS selection.

I am using Windows 8 and the only thing that worked for me was the Nexus Root Toolkit 1.6.3 where I done the Full driver configuration Guide ... but I didn't follow the instructions there I went to step 2 and only installed the Signed drivers.

I had the same problem. For me the newer version of adb is required to connect to the Nexus 7 i.e. to have the Nexus 7 ask me to "Allow USB debugging?"

In short:

Android Debug Bridge version 1.0.31 - Works

Android Debug Bridge version 1.0.29 - Does not work

Download the latest android usb drivers from

http://developer.android.com/sdk/win-usb.html#top

And then manually install these driver using Device Manager. Hope it helps!

I had faced two issues:

  1. Nexus 7 not visible to eclipse/adb when connected over usb on windows 7 64-bit using latest Jelly Bean sdk
  2. It was not showing in the 'My Computer' >> 'Portable Devices' list.

Ultimately, I found that it is an issue with the driver. Steps to resolve the issue - Open Device Manager, Uninstall the current driver (along with delete option set to yes), disconnect the device, reconnect it again, let windows install the default driver it wants, and then installed the google sdk driver again. It worked this time.

Above tells me that there is some issue with default driver and therefore, you have to delete it and re-install it. Now, it is visible in eclipse/adb and also showing in 'My Computer' also.

Install Google usb driver from SDK Manager. Later go to Device Manager, under "Other Devices" you'll see "Nexus" with the yellow exclamation mark. Right Click>Update Drivers>Let me choose>Let me pick from device drivers on my computer. Select android-sdk folder and click ok. This solved my problem

Another option is if windows updates are turned totally off on your PC. In this case even if you download the USB driver & try update it manually as described above it will not work. The only way in this case is enabling windows updating drivers automatically. Once you enabled this, remove the non-working driver from device manager & connect you tablet to the PC via USB cable. The drivers will be automatically downloaded & installed by Windows. This way worked on my Windows 7 PC.

After downloading the USB driver using the SDK manager, you can speed up the search for the new driver by telling Windows to look in the C:\Users\jdaehn\AppData\Local\Android\android-studio\sdk\extras\ folder (and sub-folders, in my case the drivers were in C:\Users\jdaehn\AppData\Local\Android\android-studio\sdk\extras\google\usb_driver)
