Mine (on an hp dv6000) is UVC, but in my research it would appear that
_very_ few programs actually support uvc yet (at least the versions in the
Ubuntu repos). luvcview does - but it's pretty much just a proof of
concept for uvc. Kopete does. Ekiga _should_ (but I couldn't make it),
and mplayer has a patch that I haven't tried.
David - what does lsusb show? The DV6000s have at least two different
webcams (only one of which is supported at all), so we need to know that,
