| /* Driver for USB Mass Storage compliant devices |
| * Debugging Functions Source Code File |
| * |
| * 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. |
| * |
| * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more |
| * information about this driver. |
