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 (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. 23 * 24 * This program is free software; you can redistribute it and/or modify it 25 * under the terms of the GNU General Public License as published by the 26 * Free Software Foundation; either version 2, or (at your option) any 27 * later version. 28 * 29 * This program is distributed in the hope that it will be useful, but 30 * WITHOUT ANY WARRANTY; without even the implied warranty of 31 * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
