I am attempting to correlate data from two obliquely angled iSight cameras in order to do 3D motion-tracking. However, when I plug in both cameras, my Mac just freaks out. The framerate fluctuates between 2000 and nearly 0, the images - if they exist - are distorted, and then Max hangs. If I look in system profiler, I can see both cameras along with two unknown devices. These two devices are apparently my root Firewire bus and the hub I'm using for the two cameras - at least that's my best guess, since unplugging the external hub makes one of them disappear. I must admit I'm a Windows native, so I don't know how to manually add and remove devices if the system isn't detecting them properly. I've tried using the same two cameras without a hub as well, so the hub is not the issue. I have tried everything I can think of including manually resetting the Firewire bus as per instructions on the Apple support site - unplug the computer for 5 minutes, then try again. Both cameras work independently, but using them both causes problems.
Quad 2.5 Ghz G5
6.5 GB Ram
Both cameras have the iSight 1.3 firmware update.
I've done a lot of searching on this, and what I can find seems to amount to many people having this problem and the few who don't saying "mine works fine..." Any suggestions?
