0008  * This driver is based on the 'USB Mass Storage Class' document. This
0009  * describes in detail the protocol used to communicate with such
0010  * devices.  Clearly, the designers had SCSI and ATAPI commands in
0011  * mind when they created this document.  The commands are all very
0012  * similar to commands in the SCSI-II and ATAPI specifications.
0013  *
0014  * It is important to note that in a number of cases this class
0015  * exhibits class-specific exemptions from the USB specification.
0016  * Notably the usage of NAK, STALL and ACK differs from the norm, in
0017  * that they are used to communicate wait, failed and OK on commands.
0018  *
0019  * Also, for certain devices, the interrupt endpoint is used to convey
0020  * status of a command.
