Right on. So for an ATAPI cdrw in an USB enclosure to work under Linux, 
the commands will have to pass the following path:

SCSI -> USB -> ATAPI

The SCSI to USB conversion is done by the Linux usb-storage driver which 
supports the Scanlogic chipset (firmware 2.6c). The USB to ATAPI 
conversion is done by the Scanlogic chip. This chip fully supports 
cd-writers, as per the enclosure manufacturer website and Scanlogic 
driver documentation.

Question still remains: does usb-storage translate SCSI cd burn commands 
correctly into USB commands?

Or course this is my simple understanding of the matter. I'll be 
standing (corrected) next to Geoff to be slapped, if needed.
