| 3 | * Driver for USB Mass Storage compliant devices |
| 4 | * SCSI Connecting Glue Header File |
| 5 | * |
| 6 | * Current development and maintenance by: |
| 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. |
