Yes, I checked on the Linux libata, it includes drivers that
assign an atapi drive to a bus on a SCSI layer. The favoured
driver is a unified ahci driver, which has full support for
device hotplugging etc and quite a few chipsets are compliant.
It sounds pretty close to our USB mass storage system.
Could it be as simple as changing the PCI addressing and the
SCSI device handles on the arm port of libata?
