My impression was that we were removing the special treatment, but not autodetection support. In other words, if you installed the drivers first, then the scripts should pick up the device as if it were any other v4l device. > Is the correct procedure that we now manually add the devices to the > config files? I don't believe so, but I'll bring it up at the next dev meeting if we can't come to a consensus here. > Also you mention v4l2src...will that work with a non v4l2 source?

Matterhorn does, but newer versions of Ubuntu no longer support v4l v1. The drivers for newer Ubuntu releases do support v4l2 so there's nothing much to worry about there.
