Yes. This isnt going to be right for all devices anyway. > Where does a CD-RW device fit into this? > And can usb-storage work in this devfs scenario? Assuming the USB scsi subset stuff includes the conventional scsi inquiry stuff then the return block from an inquiry has a type in bits 0-31 of byte 0 of the return. They dont totally define it but help a lot and I assume its how scsi devs is hacked together 0 - direct access (read disk) 1 - sequential access (read tape) 2 - printer 3 - processor (crypto etc) 4 - worm 5 - cdrom 6 - scanner 7 - optical device (Magneto Opticals and stuff) 8 - medium changer (multi-cd etc) 9 - communications 13 - enclosure Alan --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
