I was under the impression that the two drivers (umass and usscanner)
are using different means of mapping SCSI command and data transfers
onto USB transfers, but if this can integrated in umass it would
certainly be worthwhile. I just took the least resistance path of
porting the stuff as it exists in NetBSD (with a number of ideas
liberally stolen from your port of umass).

Not sure. I have disabled it due to another problem that caused panics
all over, and did not have time to re-check it afterwards.

Yep, fixed in -20020422.
