Remove it from your scenes, add it as a Global Source, then re-add it to your scenes from the global sources entry in the 'add' menu. Also, if you use a 'stream starting' scene, hide a copy of the cam behind your intro graphic. The device only initializes the first time it's used, this will get it up and running before anyone sees it, and let you transition smoothly from your intro-splash to your scene featuring face-cam, instead of jump-cutting.
