After successful enumeration, the respective device drivers come into play. For a mass
storage application, the firmware must conform to USB Mass Storage Class Bulk-Only
Transport Specification and the ATA/ATAPI protocol. The host sends a 31-byte
Command Block Wrapper (CBW). The ATAPI command is embedded in CBW.
In an ATAPI device, for each CBW received, the ATAPI packet command is issued to the
device, followed by the ATAPI command in CBW.
In an ATA device, the ATAPI command in CBW must be translated into an ATA
command, before it is issued to the device. The ATAPI command phase is followed by an
optional data phase, which is followed by a status phase. If the command is successfully
completed, the firmware must report good status in the status field of the 13-byte
Command Status Wrapper (CSW).
