1/* Driver for USB Mass Storage compliant devices

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