Well,
I took this a bit further.
Step 1) As a test measure I build a 7.10 system to give it a try with the new ZWave appl (according to the wiki:
http://wiki.linuxmce.org/index.php/Z-Wave). Exactly the same behaviour and the same errors.
Step 2) Downloaded mControl for Windows (
http://www.embeddedautomation.com/EAHAmControlDownload.htm). In the software is a nice little util to speak to the ZCU010 after you install the driver (

. After this I plugged the ZCU010 back into the core and after a few reloads........
IT WORKED. The core generated the childs and I was able to put them into a room and control them! In 10 minutes I had made an event that dimmed the lights when watching a movie, yehhhh... Rockin..
So the above proves at least my equipment is working. So this means either I did something wrong copying the setup to the core, the firmware I have on the ZCU010 is behaving differently as Linuxmce is expecting or nobody has tested this yet
