Detailed Description

This is the SCSI layer of the USB mass storage application example. This layer depends directly on the blockdev layer.

Windows peculiarities: Size of REQUEST SENSE CDB is 12 bytes instead of expected 6 Windows requires VERIFY(10) command to do a format. This command is not mandatory in the SBC/SBC-2 specification.
