[Bug 1242321] Re: USB 3.0 Harddrive not recognised

 

same problem with an ASRock Q1900DC-ITX Mainboard. 
It has 4 external ports - the 2 external USB 2 ports work without problems - but on the 2 USB 3 no device works without problems (even mouse and keyboard only work after they are pluged-out and in again after each restart).

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).
