Subject: Re: Error -71 on device descriptor read/all

[ OK, it probably seems like a faulty hardware (controller or the device 
  itself), which is not able to run at high speed, but runs nicely on full 
  speed. Do you have a chance to try another high speed device in this 
  machine to check whether it works?

  Adding linux-usb-devel into CC , just in case, and leaving the full 
  original message below ]
