USB CDRW ScanLogic: Quirk does not work?

[Federico Galvez-Durand Besnard]

Hello everyone, I have this 4 years old USB CDRW (Q-lity ECW-043) 
attached to a 4 years old Notebook (Toshiba 2805-302). I wonder whether 
someone here can give me advice about how to make it work (I guess I can 
try on my own with some hints). I have already tried different quirks on 
umass.c without success. Also, similar problems seem to be reported on 
NetBSD several years ago. There is a quirk in FreeBSD 5.3 umass.c; but 
it does not go well with this device.

Other possible solutions are:
a) Buy new hardware : it is under consideration;
b) Moving to Fedora Core 3. Well, I use BSD since NetBSD 0.8a... and 
Fedora will run much slower in this notebook;
c) Giving up on having stand alone CD backup... :(

Once attached, the device is not mounted:

I have a long dmesg here with debug ON:

I have already wrongly posted to "bugs", sorry about that.
Thank you for any help.
