GST_MESSAGE_DEVICE_ADDED never called

[Osmo Antero]

Re-hi again,

I can also see the long detection delay with gst-device-monitor-1.0 command.
Ref:
http://manpages.ubuntu.com/manpages/utopic/man1/gst-device-monitor-1.0.1.html

$ man gst-device-monitor-1.0

# In monitor mode
$ gst-device-monitor-1.0 -f
...

I am running Ubuntu 15.04 64bit.
