my free nerolinux trial is about to expire and soon I will not be able to
write to a dvd with my usb connected drive. whenever k3b is started, it
rings out the exact error as bug 165712, in both the 32 and 64 bit
version of 10.3 and the 64 bit of 11.0. The ability to write to the dvd
drive with k3b was lost with some update some time in the last six
months, but i can't pinpoint it because the write function is seldom
used. K3b is not the culprit, tried all available suse and packman
versions, same result. has anyone found an answer or workaround for this
"invalid" bug?

try...

wodim -prcap -dev=<device name>

thanks, much appreciate the constructive help. Please help finish this.
below are the outputs of your suggestions. The strange thing is that wodim
only works when the dvd is unmounted. this must be some hal mini-hell
mounting snafu that should be resolvable by knowledgeable people!

first,
tried -prcap after plugging dvd in and closing the kde "what shall i do with
the new dev" popup:
......................

For IDE/ATAPI devices configuration, see the file README.ATAPI.setup from
the wodim documentation.

second,
after *unmounting* the device wodim read it as follows:

......................

and

wodim -scanbus

continuing on, with the device still unmounted, scanbus saiz:
..............
103-32-sb1:/home/plain # wodim -scanbus

.......................

BUT, if i unplug and plug the device back in:
.........................

103-32-sb1:/home/plain # wodim -scanbus
wodim: No such file or directory.
Cannot open SCSI driver!
For possible targets try 'wodim --devices' or 'wodim -scanbus'.
For possible transport specifiers try 'wodim dev=help'.

the wodim documentation.
............................

That response does not depend on the selection on the kde deamon popup, it
stays so until the device is unmounted, physically or with "umount".



as well as

hwinfo --cdrom

the hardware info does not depend on the state of mounting and is as follows:
