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