* MSC Class Description
|
||||
* ===================================================================
|
||||
* 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))
