Upgraded to Lion, now isight camera "not connected"
I have an iMac G5 with isight on it. I upgraded to Lion and now Photobooth, Facetime and iChat say "there is no camera connected". Ive restarted my computer numerous times, and in safe mode. I've unplugged the external hard drive. The camera is not listed in System Profiler either. I've force quit applications and followed instructions to shut down using CMD, OPT, ESC. Anyone have any other advise, or having the same issue?
iMac, Mac OS X (10.7.2)
