What could be going on?

sw3@pc90313-sw3:~$ uname -a
Linux pc90313-sw3 3.11.0-13-generic #20-Ubuntu SMP Wed Oct 23 07:38:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
  • Even the newest kernel still seems to have serious problems with some USB3 controllers :( – scai Dec 9 '13 at 10:37

This was a very strange situation.

My PC is dual-boot with a Windows7. I had logged into windows for a short while, and while shutting it off, it began installing updates.

Next I logged in Ubuntu and the described problems occurred.

Going back to Windows for it to finish updating (at boot time), and then back to Linux solved the problem.

I am still wondering how did windows manage to mis-configure the very hardware.

The issue's gone now.
