Adb permissions issues with Ubuntu and Android ICS

If you encounter permissions problems when using the adb utility in Ubuntu with Android 4  ICS (Ice Scream Sandwich), try to follow this guide:

1. Find your Android device vendor id by using "lsusb".
2. echo your_vendor_id > ~/.android/adb_usb.ini
   
3. adb kill-server
4. adb start-server
5. Create or update the /etc/udev/rules.d/51-android.rules file by adding :
   SUBSYSTEM=="usb", ATTR{idVendor}=="your_vendor_id", MODE="0666"
6. sudo restart udev
7. Disconnect and reconnect your Android device
8. adb devices

Now everything should be ok!
Happy debugging!
