USB CDRW ScanLogic: Quirk does not work?

Hello, I am replying to my own message, in case it is
interesting for someone else.
I managed to mount my CDRW (using ScanLogic SL11R)
by patching umass.c (patch enclosed at the end of this
email)
Unfortunately it is not recognised as a CD device but
as a DA device.
I can do "mount -t cd9660 /dev/da0 /mnt" and read a
video file
with fairly good quality.
Now I am trying to figure out why it is not recognised
as
a CD device.
Obviously, cdrecord does not find any CDRW device.
I did not achieve my primary goal yet: write a data
CD.

Fico

patch applied to umass.c ($FreeBSD:
