The normal code path it that the read is satisfied by enough bytes read from
the USB channel. Only on failure, either in the hardware or in the data sent
to the device, the timeout is hit. So even if we request 1 ms and we get 20
ms by the bad resolution of the function, any well written program should
not be impacted, as the timeout is not hit.
