iSight doesn't work anymore, even after PRAM zap

[Egosphere]

Photobooth and such demand that I don't have an iSight any longer in my MBP. I haven't changed anything significant in my installation, so I don't know what caused this. I tried resetting the PRAM but it didn't help.

What's going on? What should I try to do to fix this?

Hmm.. What does the System Profiler say?

located in:
Applications / Utilities / System Profiler.app

Does it even acknowledge there's a iSight attached on the USB bus?

call apple while it is under warranty

No iSight on any USB Bus. (Why does it say "USB Bus" anyway? Isn't the bus redundant?) Could this be a problem in hardware?

Thanks landis, but it's definitely out of warranty.
