1 /* Driver for USB Mass Storage compliant devices
2  * SCSI Connecting Glue Header File
3  *
4  * Current development and maintenance by:
5  * (c) 1999, 2000 Matthew Dharm ([email protected])
6  *
7  * This driver is based on the 'USB Mass Storage Class' document. This
8  * describes in detail the protocol used to communicate with such
9  * devices. Clearly, the designers had SCSI and ATAPI commands in
10  * mind when they created this document. The commands are all very
11  * similar to commands in the SCSI-II and ATAPI specifications.
12  *
13  * It is important to note that in a number of cases this class
14  * exhibits class-specific exemptions from the USB specification.
15  * Notably the usage of NAK, STALL and ACK differs from the norm, in
16  * that they are used to communicate wait, failed and OK on commands.
17  *
18  * Also, for certain devices, the interrupt endpoint is used to convey
19  * status of a command.
20  *
21  * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more
22  * information about this driver.
