Ubuntu – Android Devices Not Recognized Anymore

androidusb

Ubuntu 14.04 doesn't recognize any of my Android devices anymore. (Tried with the Nexus 7 and Galaxy Nexus)

I thought this was an MTP or ADB-problem, but connecting / disconnecting the devices doesn't even change the output of lsusb or dmesg at all.

It's like the devices aren't even plugged-in. However they both charge normally, when I plug them in, so I can't imagine having a cable-problem or a problem with the android devices themselves.

(I've tried it with usb-debugging on and off on both devices – no difference)

I have problems with my Ubuntu GNOME 14.04 installation recognizing my Nexus 7 at times, too. This is what works for me:

  1. Make sure the cable can transfer information, that it's not just a power cable.
  2. Make sure you have USB debugging enabled.
  3. Unlock your device.
  4. Connect your device to your computer.
  5. Your device should display a pop-up, asking if you want to accept a connection to your computer. (If you had this pop-up before, you might have ticked the "always accept a connection from this device" checkbox.)
  6. Normally, your device should now pop up in your favorite file manager. If it doesn't, check if ADB finds your device. In a terminal, type adb devices (you might need to be root).
  7. If ADB lists your device, go to Settings > Storage and select the options button in the upper right corner:
