Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

4 | * $Id: debug.c,v 1.9 2002/04/22 03:39:43 mdharm Exp $ | ||
5 | * | ||
6 | * Current development and maintenance by: | ||
7 | * (c) 1999-2002 Matthew Dharm (mdharm-usb@one-eyed-alien.net) | ||
8 | * | ||
9 | * Developed with the assistance of: | ||
10 | * (c) 2002 Alan Stern <stern@rowland.org> | ||
11 | * | ||
12 | * Initial work by: | ||
13 | * (c) 1999 Michael Gee (michael@linuxspecific.com) | ||
14 | * | ||
15 | * This driver is based on the 'USB Mass Storage Class' document. This | ||
16 | * describes in detail the protocol used to communicate with such | ||
17 | * devices. Clearly, the designers had SCSI and ATAPI commands in | ||
18 | * mind when they created this document. The commands are all very | ||
19 | * similar to commands in the SCSI-II and ATAPI specifications. | ||
20 | * | ||
21 | * It is important to note that in a number of cases this class | ||
22 | * exhibits class-specific exemptions from the USB specification. | ||
23 | * Notably the usage of NAK, STALL and ACK differs from the norm, in | ||
24 | * that they are used to communicate wait, failed and OK on commands. | ||
25 | * | ||
26 | * Also, for certain devices, the interrupt endpoint is used to convey | ||
27 | * status of a command. | ||
28 | * | ||
