1 /* Driver for USB Mass Storage compliant devices
2 * Debugging Functions Header File
4 * $Id: debug.h,v 1.6 2001/01/12 23:51:04 mdharm Exp $
6 * Current development and maintenance by:
7 * (c) 1999-2002 Matthew Dharm (mdharm-usb@one-eyed-alien.net)
9 * Initial work by:
10 * (c) 1999 Michael Gee (michael@linuxspecific.com)
12 * This driver is based on the 'USB Mass Storage Class' document. This
13 * describes in detail the protocol used to communicate with such
14 * devices. Clearly, the designers had SCSI and ATAPI commands in
15 * mind when they created this document. The commands are all very
16 * similar to commands in the SCSI-II and ATAPI specifications.
18 * It is important to note that in a number of cases this class
19 * exhibits class-specific exemptions from the USB specification.
20 * Notably the usage of NAK, STALL and ACK differs from the norm, in
21 * that they are used to communicate wait, failed and OK on commands.
23 * Also, for certain devices, the interrupt endpoint is used to convey
24 * status of a command.
26 * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more
27 * information about this driver.
