I'm having the same issue - unable to mount my Android phone because it
gets disconnected immediately:

Title:
  USB MTP device disconnected automatically

Status in “linux” package in Ubuntu:
  New

Bug description:
  On connecting an android device in MTP mode to my ubuntu laptop, it
  showed up as an MTP device. After some time it stopped showing the
  device. On connecting and dis-connecting the device multiple times,
  dmesg doesn't show any output (Didn't get the dmesg output this time).
  Even after rebooting the device is not detected. Tried reboot multiple
  times. dmesg shows that the device was detected and immediately
  disconnected.

  Same thing works on windows dual boot on same machine. So don't think
  it is a hardware issue. Also had the same issue on my office machine
  as well. Was working properly on 12.04 on office machine.
