This is a problem (I see it from time to time) when the USB
stack or hardware wets itself.  Some of my solutions have been
*  disconnect and reconnect the device...
*  use a different USB port
*  if an external USB hub is involved, disconnect and reconnect
   that (sometimes certain ports fly south for no obvious reason)
*  if needed, disconnect and reconnect power to any USB hubs or
   other devices (like if your device gets powered elsewhere)
*  if nothing else works, reboot your machine,
*  if that fails, completely power-cycle your machine, so that
   all hardware has a chance to reset and start from cold state.

In exceptional cases, your hardware could have somehow been
damaged, if a particular USB port always gives this type of error.

hope that's useful
