   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.
  21  *
  22  * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more
  23  * information about this driver.
