I have a frustrating problem ! My external iSight camera has stopped working, ever since I moved from a PPC G5 to an Intel Mac Mini. I did actually have it working for a while, but I must have changed something and now nothing I do will get it to work again.
I have tried isolating the problem by removing other Firewire devices - the camera is always correctly recognised no matter where I plug it in; System Profiler shows it as present, and it is shown as available as a video or sound source. The problem is that when I actually try to use it, I just get blank (black) and no sound input.
If I plug the camera into another machine, it is recognised and works OK !
I'm sure this must be a software conflict, but I don't know what with. Console logs just show similar messages from any application that tries to use the camera, saying that it's unable to open the source for input. I'm suspecting that some 3rd party plugin or driver is being loaded and crashing out - perhaps because I migrated over from a non-Intel machine (I did a clean install, and ran the migration assistant).
Any suggestions how to find the culprit ?
