It is because we are attaching drivers per interface instead of per device. A 
new modem unit is allocated every time we find a modem, simply put. If the 
modem has multiple instances in an interface, /dev/cuaU0.[0...] will be 
created. Else /dev/cuaU... .

Have you tried "cat /dev/null > /dev/da0", to refresh the label on the disk?
NOTE: /dev/null is not /dev/zero

Same with "da1"

Maybe your device needs a quirk, because it hangs on one of the issues SCSI 
commands. Have you looked at:

No, but you can try the following command which gives a nice overview:
