The problem is that it DID work.
I could boot with both cams connected, devd would start two instances of
webcamd, one for each camera, and there was corresponding /dev/video? files.
Some time after n244736-dba7b0ef928 it stopped working, and now only one
instance is started. If I try to start it manually with 'service webcamd
start ugen2.4' it says "webcamd already running?"
Starting webcamd directly, not using the service command, it works:
# webcamd -d ugen2.4 -B
webcamd 20157 - - Attached to ugen2.4[0]
