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