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. 22 * 23 * This program is free software; you can redistribute it and/or modify it 24 * under the terms of the GNU General Public License as published by the 25 * Free Software Foundation; either version 2, or (at your option) any 26 * later version. 27 * 28 * This program is distributed in the hope that it will be useful, but 29 * WITHOUT ANY WARRANTY; without even the implied warranty of 30 * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
