A lot of this depends on the revision of the 
QuickCam Fusion (this applies to most of the 
Logitech cameras from the QuickCam Pro 5000 and 
newer).

At the moment we provide only a video driver for 
the camera -- the audio interface is handled by 
the Apple USB Audio Class driver.

The issue is that some version of the camera 
don't implement the USB Audio Class specification 
correctly in a way that is incompatible with the 
Apple drivers (but happens to work on Windows).

Also, some of the older cameras are Composite 
Class devices with a Vendor Specific video 
interface -- the newer camera are Miscellaneous 
Class devices with a USB Video Class video 
interface -- these will work with the Apple USB 
Video class driver shipped on Mac OS X 10.4.6 (?) 
and newer -- although I'd recommend 10.4.8 or 
newer, due to some USB bugs in 10.4.6 and 10.4.7.

We will share the camera with the Apple driver -- 
you should see both as inputs -- but many of the 
camera features will not be available with the 
Apple driver.

Also, on older versions of Mac OS, if you have a 
Miscellaneous Class (newer) camera, the mic won't 
be visible to the Apple driver because the OS 
doesn't know about miscellaneous class.

If you send me the output from USB Prober for you 
camera (and tell me what OS version you're 
running), I may be able to give you a better 
answer.
