 /* Driver for USB Mass Storage compliant devices
  * Debugging Functions Source Code File

  * $Id: debug.c,v 1.9 2002/04/22 03:39:43 mdharm Exp $
  *
  * Current development and maintenance by:
  *   (c) 1999-2002 Matthew Dharm (mdharm-usb@one-eyed-alien.net)
  *
  * Developed with the assistance of:
  *   (c) 2002 Alan Stern <stern@rowland.org>
  *
  * Initial work by:
  *   (c) 1999 Michael Gee (michael@linuxspecific.com)
  *
  * This driver is based on the 'USB Mass Storage Class' document. This
  * describes in detail the protocol used to communicate with such
  * devices.  Clearly, the designers had SCSI and ATAPI commands in
  * mind when they created this document.  The commands are all very
  * similar to commands in the SCSI-II and ATAPI specifications.
  *
  * It is important to note that in a number of cases this class
  * exhibits class-specific exemptions from the USB specification.
  * Notably the usage of NAK, STALL and ACK differs from the norm, in
  * that they are used to communicate wait, failed and OK on commands.
  *
  * Also, for certain devices, the interrupt endpoint is used to convey
  * status of a command.
  *
