1 /* 2 * Driver for USB Mass Storage compliant devices 3 * SCSI Connecting Glue Header File 4 * 5 * Current development and maintenance by: 6 * (c) 1999, 2000 Matthew Dharm (mdharm-usb@one-eyed-alien.net) 7 * 8 * This driver is based on the 'USB Mass Storage Class' document. This 9 * describes in detail the protocol used to communicate with such 10 * devices. Clearly, the designers had SCSI and ATAPI commands in 11 * mind when they created this document. The commands are all very 12 * similar to commands in the SCSI-II and ATAPI specifications. 13 * 14 * It is important to note that in a number of cases this class 15 * exhibits class-specific exemptions from the USB specification. 16 * Notably the usage of NAK, STALL and ACK differs from the norm, in 17 * that they are used to communicate wait, failed and OK on commands. 18 * 19 * Also, for certain devices, the interrupt endpoint is used to convey 20 * status of a command. 21 * 22 * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more 23 * information about this driver. 24 * 25 * This program is free software; you can redistribute it and/or modify it 26 * under the terms of the GNU General Public License as published by the 27 * Free Software Foundation; either version 2, or (at your option) any 28 * later version. 29 * 30 * This program is distributed in the hope that it will be useful, but 31 * WITHOUT ANY WARRANTY; without even the implied warranty of 32 * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
