I have a customer using red hat 9 and I recently installed (after much hassle figuring it out) k3b's latest version (I don't like any other linux burning software)
and she has four nec nr 7800b burners which is not natively supported by linux
I haven't seen any drivers for it either.
None of the burning software I tried recognizes it
I did cdrecord-scanbus and it only picked up the cd rom drive
I can use the burner for read access though.
