SONY believe they know better.. so they didn't impliment the standard SCSI-2 audio commands but used their own.. (I mean no-one uses these devices without BIOS support right?) I THINK there may be a version of one of the cd player packeges (I forget which) that uses the scsi(4) interface to do direct scsi commands to the device. it possibly knows about the sony.
