title: Adb returns "device not found" in recovery mode
body: <p>I try to access an android device (Samsung Galaxy Y) through usb using adb. When the phone is running as usual, with USB debugging activated, adb works just fine and I see the device with a call to "adb devices". However I need adb access in the recovery mode (I want to execute fsck on /data and thus need to unmount it first). I reboot the phone in recovery mode and run CWM (ClockworkMod ROM Manager) but then the phone does not show up with "adb devices".</p>
  
  <p>I looked this up and it appears that on windows systems the solution is to change the drivers. However I am on Ubuntu 14.04 LTS and I am stuck with my problem. I tried several suggestions of udev rules in /etc/udev/rules.d but none worked for me.</p>
  
  <p>How can I solve this issue ?</p>
