Title:
  USB 3.0 Harddrive not recognised

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu is not recognising any device plugged into any USB 3.0 ports.
  Sometimes Ubuntu will freeze for a few seconds when you plug something
  into a USB 3.0 port; when Ubuntu comes out of the freeze, the device
  is still NOT recognised.

  No problems with USB 2.0 ports and devices.

  The USB 3.0 on this computer only works in Windows 7 (I'm dual booting
  Ubuntu 13.10 and Windows 7, both are 64-bit).
