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