  1. /*
  2. * Header file for Special Initializers for certain USB Mass Storage devices
  3. *
  4. * Current development and maintenance by:
  5. * (c) 1999, 2000 Matthew Dharm (mdharm-usb@one-eyed-alien.net)
  6. *
  7. * This driver is based on the 'USB Mass Storage Class' document. This
  8. * describes in detail the protocol used to communicate with such
  9. * devices. Clearly, the designers had SCSI and ATAPI commands in
  10. * mind when they created this document. The commands are all very
  11. * similar to commands in the SCSI-II and ATAPI specifications.
  12. *
  13. * It is important to note that in a number of cases this class
  14. * exhibits class-specific exemptions from the USB specification.
  15. * Notably the usage of NAK, STALL and ACK differs from the norm, in
  16. * that they are used to communicate wait, failed and OK on commands.
  17. *
  18. * Also, for certain devices, the interrupt endpoint is used to convey
  19. * status of a command.
  20. *
  21. * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more
  22. * information about this driver.
