Hi, yep, Philips SPC900NC connected at a MacMini 1.66 CoreDuo (directly 
without a hub).
What I noticed is that most of the crashes happen when Skype is running 
and has successfully detected the cam and you plug in some other usb 
equipment, or plug one of, so the driver appears to re-initialize the 
cam (the led burns for a second). The next time you want to start cam 
function in skype it crashes.
Unluckily that happens from time to time although there hadn't been any 
manipulations on usb devices...
