This is still present in vivid.

Switching to the performance govenor, removing the drive and re-adding
it worked around the bug.

Something must be blocking power to the xhci when the cpu is saving
power...?

This is also present on non-Ubuntu systems, including ones running
Linus’ latest kernels.

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).
