Asus Nexus 7 not recognized by Android dev tools v

Question

Problem: Asus Nexus 7 not recognized by adb when correctly installed and connected

Setup: Asus Nexus 7 tablet Windows 7 64 bit OS

Steps taken:

1. Installed 64 bit Java JDK (http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html)
2. Installed Android SDK (http://developer.android.com/sdk/index.html)
3. Installed Google USB driver (http://developer.android.com/tools/extras/oem-usb.html)
4. Set tablet to USB debugging mode

In the Windows Device Manager, the Nexus is recognized as an Android Device via Android Composite ADB Interface. The device status indicates it is connected and working properly, running driver version 7.0.0.1 (8/27/12 update) from Google.

However, when I run adb devices at the command prompt (in the sdk/platform-tools directory), the Nexus does not come up as an attached device - the list is empty.

Does anyone have any insight on what the problem might be? I have tried uninstalling and reinstalling all drivers, restarting the computer each time. I have tried a variety of usb ports and cables, as well as switching between MTP and PTP connections with no success.

Answer 1

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.!

Answer 3

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

http://forum.xda-developers.com/showthread.php?t=1989777

"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.

Answer 4

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

Answer 5

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.

Answer 6

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!
