  1. /* Driver for USB Mass Storage compliant devices

  6. * Current development and maintenance by:
  7. * (c) 1999, 2000 Matthew Dharm (mdharm-usb@one-eyed-alien.net)
  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.
