^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) * This driver is based on the 'USB Mass Storage Class' document. This
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) * describes in detail the protocol used to communicate with such
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) * devices. Clearly, the designers had SCSI and ATAPI commands in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) * mind when they created this document. The commands are all very
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) * similar to commands in the SCSI-II and ATAPI specifications.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) * It is important to note that in a number of cases this class
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) * exhibits class-specific exemptions from the USB specification.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) * Notably the usage of NAK, STALL and ACK differs from the norm, in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) * that they are used to communicate wait, failed and OK on commands.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) * Also, for certain devices, the interrupt endpoint is used to convey
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) * status of a command.
