/* Driver for USB Mass Storage compliant devices
|
|
* Debugging Functions Header File
|
|
*
|
|
* Current development and maintenance by:
|
|
* (c) 1999-2002 Matthew Dharm (mdharm-usb@one-eyed-alien.net)
|
|
*
|
|
* 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.
|
|
*
|
|
* Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more
|
|
* information about this driver.
