No. What happens when you use/load "umass" and unload "atausb" ?

Everything works nice with umass. It creates the da0 device node.
It just shows up these errors, as it always did...
GEOM: new disk da0

I had these messages with two other devices before, an MP3 player and a
USB floppy drive. I fixed these errors by adding a quirk to
/sys/cam/scsi/scsi_da.c.

Instead of having all these quirks, isn't it possible that the SCSI layer can
auto-probe this?
