That's a start. I see the media_server messages, but not the nodes one. The
only
messages I get regarding the usb_webcam media addon is

NodeManager::RegisterAddon:: ref-name "usb_webcam.media_addon", assigning id
5

but I don't see the messages of the addon itself, which contains two webcam
drivers.

The problem is that I'm totally new to both the media_server and addons.
I'll
see if I can gather some info by looking at other working code.

My main concern though , was to understand why my webcam doesn't appear
anymore in the media window under video, so I can fix the code I added.
