1 /* Header file for Special Initializers for certain USB Mass Storage devices
2  *
3  * Current development and maintenance by:
4  *   (c) 1999, 2000 Matthew Dharm (mdharm-usb@one-eyed-alien.net)
5  *
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.
11  *
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.
16  *
17  * Also, for certain devices, the interrupt endpoint is used to convey
18  * status of a command.
19  *
20  * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more
21  * information about this driver.
