Title:
  USB randomly stops working on Kubuntu 12.04

Status in linux package in Ubuntu:
  Expired

Bug description:
  I am using a laptop and all the USB ports will suddenly stop working
  especially when the laptop has been put to sleep and then resumed
  again (however the probability is very rare) . USB mouse, keyboard,
  flash drives will not be detected when plugged into any of the USB
  ports.
