I want to be able to connect my Nexus 7 in order to test my applications from Eclipse on the physical device.

I followed this Google guide.

My /etc/udev/rules.d/51-android.rules file contains this :

SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e42", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e40", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e41", MODE="0666"

The device is configured to use "Camera (PTP)" and "USB debugging" is checked too.

But adb devices lists no device.

What have I missed ?

The fact that the "Connected" message only appeared sometimes and that lsusb was unable to detect the Nexus casted a doubt on the cable.

I just tested with another cable and it works. My other cable seems to have a damaged connector.

  • As I saw many times since that ADB connectors are fragile and very susceptible to this kind of problem, I keep this answer which might help other people. There's obviously a flaw in the design of those connectors. Commented Jan 6, 2014 at 17:28
