I doubt either of them forces users to hack up flags for these cases. At least for windows I suspect it just never sends the LUN encoded in the CDB and treats USB devices special instead of our insistance on pretending they are SCSI-2. Maybe some of the USB people have on the wire traces or access to device or windows documentation on this?
