* This module manages the MSC class V1.0 following the "Universal
* Serial Bus Mass Storage Class (MSC) Bulk-Only Transport (BOT) Version 1.0
* Sep. 31, 1999".
* This driver implements the following aspects of the specification:
* - Bulk-Only Transport protocol
* - Subclass : SCSI transparent command set (ref. SCSI Primary Commands - 3 (SPC-3))
