|  | * 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. |
