  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.
