+ * ===================================================================
+ * 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))
