i found a deal on an iSight camera, but have a problem. My MacBook has a 6 pin FireWire port. I plug the camera in and everything works. Of course it already has a camera, so I don't need it. I bought a 9 pin to 6 pin adapter so I can use the iSight on my 2009 MacPro. When I plug it in, the little green light on the camera lights up for a second, then goes out. The MacPro doesn't recognize that the camera is attached. Has anyone else run into this before? Thanks!!
