If you are using OSX there is no Gem support for anything but firewire cameras!

(probably due to the fact that web-cams offer very poor quality and no real
performance gain on OSX)

That being said the now discontinued iBot cameras from orange micro are web-cam
quality and do work with gem (though apparently they shouldn't)

If you want USB (or quicktime capture support) in Gem then ask on the
gem-dev at iem.at list or perhaps the regular pd list. (hmmm there may be a feature
request tracker for gem... nope only PD not Gem.)

Otherwise you can use a fire-wire camera or get a DV bridge and use an analog
camera. Both will give you much better quality and much less noise than a
web-cam. For tracking a web-cam is barely useful.
