   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.
