@Mateusz:

So far, I've only seen the problem with USB autosuspend breaking USB3
ports on AMD-based chipsets. Specifically, for me, I see the problems on
A85X and A88X systems. I haven't had a chance to test the A85X system,
but disabling USB autosuspend on the A88X system definitely avoids the
problem.

I notice from your dmesg output in comment 5 that you have an Intel
chipset, so you might actually have a different problem. Sorry. :-(

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).
