Hello again, garygg
Thanks for letting me know you found my post "Helpful".
I agree that the "C" in your part number indicates Rev C. However, I do not think that
External iSight Model Version Revision matters to your problem.
I know of no software that will damage external iSight. Neither do I know of software or software commands that will repair a damaged one.
You seem to have tested all possibilties other than a known working iSight on your home Macs to prove their condition. With all you have tried, I doubt that the work-G5 test will result in a working iSight. However, if your iSight works on
any Mac, we can explore unlikely possibilities such as both your home Mac's having faulty ports or Firewire circuits.
I would not give up on repairing my external iSight until I got a repair cost estimate, but you may have a better feel for expected costs than I.
If you do opt for a different camera to use with your existing Macs, consider the suggestions
this post on alternatives to external iSight. Leopard supports all the alternatives mentioned there, including UVC. You seem to be an experienced Mac user, and you may already know whether your hardware accelerator software supports all the alternatives. If not, check with the processor-upgrade manufacturer for possible known issues with some of the options I mention.
We will watch for your status update.
Cheers,
EZ
