7 | * (c) 1999, 2000 Matthew Dharm (mdharm-usb@one-eyed-alien.net) | ||
8 | * | ||
9 | * This driver is based on the 'USB Mass Storage Class' document. This | ||
10 | * describes in detail the protocol used to communicate with such | ||
11 | * devices. Clearly, the designers had SCSI and ATAPI commands in | ||
12 | * mind when they created this document. The commands are all very | ||
13 | * similar to commands in the SCSI-II and ATAPI specifications. | ||
14 | * | ||
15 | * It is important to note that in a number of cases this class | ||
16 | * exhibits class-specific exemptions from the USB specification. | ||
17 | * Notably the usage of NAK, STALL and ACK differs from the norm, in | ||
18 | * that they are used to communicate wait, failed and OK on commands. | ||
19 | * | ||
20 | * Also, for certain devices, the interrupt endpoint is used to convey | ||
21 | * status of a command. | ||
22 | * | ||
