Title:
  [Dell Precision M3800] USB is dead after resume from sleep

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  After resuming from sleep (suspend to ram), all external usb ports are
  dead.

  The laptop's built in keyboard and synaptic touch pad (I think it is
  vonnected via internal usb, but not 100% sure) still work.

  Only a complete power down and reboot seem to bring back the devices.

  The problem does not happen with the previous kernel 3.13.0-36.
