This 81da177e4SLinus Torvalds * describes in detail the protocol used to communicate with such 91da177e4SLinus Torvalds * devices. Clearly, the designers had SCSI and ATAPI commands in 101da177e4SLinus Torvalds * mind when they created this document. The commands are all very 111da177e4SLinus Torvalds * similar to commands in the SCSI-II and ATAPI specifications. 121da177e4SLinus Torvalds * 131da177e4SLinus Torvalds * It is important to note that in a number of cases this class 141da177e4SLinus Torvalds * exhibits class-specific exemptions from the USB specification. 151da177e4SLinus Torvalds * Notably the usage of NAK, STALL and ACK differs from the norm, in 161da177e4SLinus Torvalds * that they are used to communicate wait, failed and OK on commands. 171da177e4SLinus Torvalds * 181da177e4SLinus Torvalds * Also, for certain devices, the interrupt endpoint is used to convey 191da177e4SLinus Torvalds * status of a command. 201da177e4SLinus Torvalds * 211da177e4SLinus Torvalds * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more 221da177e4SLinus Torvalds * information about this driver. 231da177e4SLinus Torvalds * 241da177e4SLinus Torvalds * This program is free software; you can redistribute it and/or modify it 251da177e4SLinus Torvalds * under the terms of the GNU General Public License as published by the 261da177e4SLinus Torvalds * Free Software Foundation; either version 2, or (at your option) any 271da177e4SLinus Torvalds * later version. 281da177e4SLinus Torvalds * 291da177e4SLinus Torvalds * This program is distributed in the hope that it will be useful, but 301da177e4SLinus Torvalds * WITHOUT ANY WARRANTY; without even the implied warranty of 311da177e4SLinus Torvalds * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
