1 /* Special Initializers for certain USB Mass Storage devices
3 * Current development and maintenance by:
4 * (c) 1999, 2000 Matthew Dharm (mdharm-usb@one-eyed-alien.net)
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.
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.
17 * Also, for certain devices, the interrupt endpoint is used to convey
18 * status of a command.
20 * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more
21 * information about this driver.
