>Description:

My externeal usb DVD drive is showing up as 'da' rather than as 'cd'
when using usb2_storage_mass.  When I load usb2_storage_ata it shows
up as a 'cd' device that's usable.  mass should behave as well as ata
in this case, or it should detect that it can't get it right and
refuse to attach things.

>How-To-Repeat:

I loaded all the usb2 drivers at runtime:

kldload usb2_controller_{e,o}hci
kldload usb2_sotrage_mass

I then plugged in the drive.  This is an external DVD drive.
