Yes, it is still the same problem:

Some comments:

This was my original post:
http://lists.freebsd.org/mailman/htdig/freebsd-usb/2004-December/000318.html

I went through my files and found some work I did and reported to this list:
http://lists.freebsd.org/mailman/htdig/freebsd-usb/2005-February/000660.html

As far as I remember, I managed to mount this CDROM and use it in RO mode.
I could not make the kernel recognise it as a RW device.
At that time, I got many cheap working flash drives > 512MB and a new 
machine, so this machine (PIII at 800MHz/384MB mem) was assigned to a 
mission in which backup on CD was no longer necessary.
This hacking was no longer a priority.

And now I guess I did not report my work in the right way because I 
can't see these messages:
