  7  *
  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.
