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 | * | |
23 | * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more | |
24 | * information about this driver. | |
