   8 commit 62e6d1e59c77316768a663d1328390b4cd33801f upstream.
   9
  10 If USB cable is connected prior to boot, we don't get any interrupts
  11 so we must manually check the VBUS state and report it during probe.
  12 If we don't do it then USB controller will never know that peripheral
  13 cable was connected till the user unplugs and replugs the cable.
