The ide-scsi deprecation doesn't affect usb-storage at all, just emulating
SCSI over IDE is affected. USB Storage is really SCSI on top of another
protocol, and SBP2 (FireWire) is the same way.
Actually, all ATAPI drives support the SCSI command set and provide a way to
send SCSI commands to the controller. Simply put, ide-scsi mapped SCSI
commands to IDE (lookup table approach), when all you really needed to do was
use the IDE command for 'send this SCSI command'.
