#256 Creative Live VF0470 is not working

[Anonymous]

I bought this Cam because it has good chance working on MacBook. Well, I installed the latest Macam (2/9/09 build), and plug in the Web cam. No light, and no picture. Its as if the Webcam is broken!!??? Then I tested the same webcam on XP, and it works there. Any ideas?
Mac config: Intel Core Duo with Leopard
