Title:
  usb2 port does not work.

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  My laptop has two usb ports, one 2.0 and the other 3.0. The 3.0 works
  correctly (as far as i can see). The usb 2.0 port does nothing. It
  seems to have power (a mp3 player took charge, but a cellphone did
  not) but shows no activity otherwise. Whatever I plug in it nothing
  happens. Nothing in dmesg, nor anything changes in lsusb. I've tried
  wireless mouse, pendrive, hdd, couple cellphones. Everything works in
  the 3.0 port, does not in the 2.0 port.

  The laptop is a Sony VAIO T13. It's a "ultrabook", with everything
  intel inside.
