The draft "CAP Working Group minutes - Nov 9-10, 2004"
document noted that the ATA command pass through (16)
SCSI command has been allocated opcode B5h.

That is a 12 byte opcode which SPC-3 rev 21a lists as
"Trusted computing Out [proposed]". Perhaps B5h is a
typo and should be 85h which is an unused 16 byte command.
