31da177e4SLinus Torvalds  * Current development and maintenance by:
41da177e4SLinus Torvalds  *   (c) 1999, 2000 Matthew Dharm (mdharm-usb@one-eyed-alien.net)

61da177e4SLinus Torvalds  * This driver is based on the 'USB Mass Storage Class' document. This
71da177e4SLinus Torvalds  * describes in detail the protocol used to communicate with such
81da177e4SLinus Torvalds  * devices.  Clearly, the designers had SCSI and ATAPI commands in
91da177e4SLinus Torvalds  * mind when they created this document.  The commands are all very
101da177e4SLinus Torvalds  * similar to commands in the SCSI-II and ATAPI specifications.
111da177e4SLinus Torvalds  *
121da177e4SLinus Torvalds  * It is important to note that in a number of cases this class
131da177e4SLinus Torvalds  * exhibits class-specific exemptions from the USB specification.
141da177e4SLinus Torvalds  * Notably the usage of NAK, STALL and ACK differs from the norm, in
151da177e4SLinus Torvalds  * that they are used to communicate wait, failed and OK on commands.
161da177e4SLinus Torvalds  *
171da177e4SLinus Torvalds  * Also, for certain devices, the interrupt endpoint is used to convey
181da177e4SLinus Torvalds  * status of a command.
