The sly dogs!! Sorry to get our hopes up guys
However, I have found a true USB2 webcam by
Creative - "WebCam Live! Ultra". It has a CCD and not a cmos as it's siblings do, but I haven't managed to find out specifically what chip. Goes for ~$160 from online retailers.... maybe worth checking out??
Edit:
There's also the
Logitech Fusion, but doesn't seem to have reached our shores yet.
Wonder why Philips are mucking around with "USB2 compatible", while it's competitors are creating true USB 2 webcams?
