Instead of compiling the scsi.c cups backend (and  the scsi-linux.c if needed), perhaps you 
consider looking for USB to SCSI adapters for the respective hardware and OS.
This because most of the deviations from the "standard USB protocol“ can be handled
by the usb quirks approach provided by cups, but – from my (though a couple of years old) experience
with SCSI – cards there are lots of vendor specific peculiarities with SCSI controllers which sometimes
may be hard to represent by software.
