Hmm, my Deneb and Posiden recognizes my new CDROM, but not for long. Poseidon repots:
Device USB TO IDE probably dropped dead.
Automatically powercycling port for 'USB TO IDE' due to death event.
Zapping device 'USB to IDE' at port 3
'USB TO IDE' retreated, pitiful coward.

pitiful indeed
I am using usbscsi.device at UNIT 0 in my DOS mount , but I don't really get that far, all this happens well before I get to any device mounting.
Any ideas? I'm gonna go check if there is an update for Poseidon ...
