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'.
