Looks pretty standard.  Here is more info on the possible quirks:
http://www.root.org/~nate/freebsd/quirks.html

If I were you, I'd look first into adding one for RS_NO_CLEAR_UA in
sys/dev/usb/umass.c.  See other quirks like this to get an idea.  It's
also possible that the problem is "NO_SYNC_CACHE" in
sys/cam/scsi/scsi_da.c.  I'm adding Kevin Oberman.  He's submitted some
quirks before.  The idea is to try a few similar to the surrounding ones
until something works.

The reason is that there never was a quirk for your device.  "OLD" implies
there was already one there.
