^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12)  * This driver is based on the 'USB Mass Storage Class' document. This
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13)  * describes in detail the protocol used to communicate with such
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14)  * devices.  Clearly, the designers had SCSI and ATAPI commands in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15)  * mind when they created this document.  The commands are all very
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16)  * similar to commands in the SCSI-II and ATAPI specifications.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17)  *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18)  * It is important to note that in a number of cases this class
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19)  * exhibits class-specific exemptions from the USB specification.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20)  * Notably the usage of NAK, STALL and ACK differs from the norm, in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21)  * that they are used to communicate wait, failed and OK on commands.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22)  *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23)  * Also, for certain devices, the interrupt endpoint is used to convey
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24)  * status of a command.
