9  * This driver is based on the 'USB Mass Storage Class' document. This
10  * describes in detail the protocol used to communicate with such
11  * devices.  Clearly, the designers had SCSI and ATAPI commands in
12  * mind when they created this document.  The commands are all very
13  * similar to commands in the SCSI-II and ATAPI specifications.
14  *
15  * It is important to note that in a number of cases this class
16  * exhibits class-specific exemptions from the USB specification.
17  * Notably the usage of NAK, STALL and ACK differs from the norm, in
18  * that they are used to communicate wait, failed and OK on commands.
19  *
20  * Also, for certain devices, the interrupt endpoint is used to convey
21  * status of a command.
