I have the same problem, except that I have a supported Que USB drive with one of the Mitsumi drive mechanisms. I tried everything I could think of. Maybe you'll have some luck with what I've tried. I installed Mac OS 9.1, it says it's required for burning with 3rd party. Turned off my other CD burning software extentions, in case of a conflict. Made sure I installed the USB authoring extension. But, it still doesn't work.
Anyone out there know how to fix this problem?
