I have just connected a usb web cam but my g5 imac doesn't see it. When I try to chat with it I am told there is no camera
Hey there,
I just realized, its a USB camera, iChat is not designed to work with USB cameras, only firewire... However, if you go to VersionTracker.com and download this program, it allows USB cameras to work with iChat, the link is below.

I hope this helps! Let me know!
