No, atabus and umass are at the same level in the config herarchy.
Both offer a way to transfer data from/to a wd device, but do it in a different
way: atabus drive the wd device directly from its register, while
umass talks to a ata/usb bridge which hide the ATA registers from us.

Back to umass and scsi:
scsibus* at scsi? should be enouth to have a scsibus attach to umass.
If it doesn't there is a bug somewhere (a missing scsi attribute ?)
