Hi Skipper,
It depends a bit on the operating system you are using and whether or not you've installed the appropriate driver, firmware, and/or software.
Here's the main support page for the HP kq246aa Deluxe Webcam: http://h10025.www1.hp.com/ewfrf/wc/searchResults?tmp_product=HP+Deluxe+Webcam&product=3737180&tmp_qt=support&cc=us&dlc=en&lc=en.
You can download manuals and quick start guides here: http://h10025.www1.hp.com/ewfrf/wc/manualCategory?cc=us&dlc=en&lc=en&product=3737180&.
Here's how to contact Technical Support for the Webcam: http://h10025.www1.hp.com/ewfrf/wc/contacthp?cc=us&dlc=en&lang=en&lc=en&product=3737180&task=.
Or perhaps you can find help in the HP forums (just like here but for things like your Webcam): http://h30434.www3.hp.com/t5/Other-HP-Consumer-Products-and/bd-p/Other1.
If you just got it, I'd first try just calling techical support for free in-warranty assistance. If you've had it a while, you may want to try the other options first.
I hope this helps.
Good luck!
