   8 *
   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.
  22 *
  23 * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more
  24 * information about this driver.
