1 : /* Driver for USB Mass Storage compliant devices
2 : * SCSI Connecting Glue Header File

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