Hi,
Cameras do not appear in the Finder list of Drivers or Memory devices like some did in OS 9
If the System Profiler "Sees" it then the next thing to try is if different apps can access it.
iMovie can see many formats from many cameras.
I have a Analogue Camcorder that I can play through a DV Converter.
the DV Converter can be set to pass-through the Analogue signal and iMovie can see it.
It of course can see the DV signal.
Photo Booth will see most USB Cameras even if you have USB 1.1 ports if you have a Mac Driver for what ever camera it is.
iChat is the fussiest in this respect.
Originally it would only see DV input from the Firewire iSight. This was in fact any DV input over firewire and included other DV Firewire webcam and DV firewire Camcorders.
The Utility iSUBCam added the ability to use the external iSight on Macs with lower than G3/600mghz specs AND to use certain USB Cameras.
It has been updated several times to work with newer cameras and the OS.
At 10.4.9 Apple introduced a UVC driver (USB Video Class) into the OS so that UVC compliant (Vista Certified) cameras could be used over USB 2.0 able computers without the need for another driver.
(this does not need the iSUBCam Utility)
Can you see pictures in other applications ?
