Title:
  Suspend problem when running LiveUSB from USB 3.0 port (but not 2.0
  port)

Status in linux package in Ubuntu:
  Expired

Bug description:
  When running Ubuntu 14.04/14.10 from LiveUSB, the system would crash
  after suspend (either by closing the lid or forcing the system to
  suspend), when the USB stick was inserted into USB 3.0 port.

  This problem was experienced with both USB 2.0 and 3.0 stick.

  No problem was observed when the Ubuntu LiveUSB stick (either USB 2.0
  or 3.0) was inserted into a USB 2.0 port. (I.e., the Ubuntu system
  would wake up normally after suspend when USB 2.0 port was used).

  When I installed 14.04/14.10 into a USB stick (3.0), Ubuntu would wake
  up normally from suspend (i.e. no problem with the USB 3.0 port with
  an installed USB stick).

  It thus appears that this is not a BIOS problem. The suspend (or more
  specifically, wake-up) problem only occurred when booting from a
  LiveUSB stick (USB 2.0/3.0) in a USB 3.0 slot.

  Update:  With Ubuntu 15.04, I was able to wake up the LiveUSB when it
  was on USB 2.0 stick in a USB 3.0 port, but not on USB 3.0 stick.
