Ok at least I got it working now.
got a hold of possy on IRC and he helpt me out to get it started.
here is what I did:
check if the com is working correctly.
install the chromoflex package manualy because there is only rx on the chromoflex so no autodetection possible.
removed the non working device
rebooted the md
added a new chomoflex
set the baudrate to B9600
only thing I want to do is to be able to have the moodlight effects back and be able to turn it on and of with a switch connected to t-wires
anyone have an idea on how to do that.
I think the chromo off command doesn't work as it should, but I have to talk to hari about that.
opening a new topic on that in the user section
