Comments:
This request sends a USB Reset over the bus. As a result of this all pending transactions
on the bus should be aborted. This request causes all of the status and configuration
values associated with endpoints in the affected interfaces, to be set to their default
values. After resetting the Device, the OS selects the active configuration and the
interfaces within it, so that the Device remains configured. All handles to Device and
pipe objects remain valid. This request should not appear on any unconfigured Device.
