GST_MESSAGE_DEVICE_ADDED never called

[Osmo Antero]

Hello,

Check system messages with dmesg to see if the kernel detects your camera.
$ dmesg -wH
...

You may also study how audio-recorder handles new and removed audio-input
devices.
Ref:
http://bazaar.launchpad.net/~audio-recorder/audio-recorder/trunk/view/head:/src/gst-devices.c

Sometimes it takes upto 5 - 6 seconds before audio-recorder (or Gstreamer)
reacts to new hw.
Audio-recorder has also a refresh-button to reload the device list.
Disconnected devices are handled immediately.
