I've been doing Android development for a while, but udev didn't like my new Nexus 7. adb devices gave a cryptic error:
Code:
List of devices attached
????????????   no permissions
From http://stackoverflow.com/questions/3429959/why-is-eclipses-android-device-chooser-not-showing-my-android-device I created a file /etc/udev/rules.d/51-android.rules containing (based on lsusb output)
Code:
SUBSYSTEM=="usb", SYSFS{idVendor}=="18d1", MODE="0666"
and set sudo chmod a+r /etc/udev/rules.d/51-android.rules. After restarting udev with sudo /etc/init.d/udev restart and also restarting ADB with adb kill-server everything now works perfectly:
Code:
john@sisig ~/Desktop $ adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached

"/etc/udev/rules.d/51-android.rules" fixed the problem for me as well. Thank you.
