My Surfaces (Mix and Controll) are not shown

I make a fresh install.
iMac 5k 2015 (i7 4.0GHz)
OSX 10.11.1
EuControll 3.3.2
Euphonix Mix and Euphonic Controll connected withSitcom USB-Ethernet Adapter
The 2 surfaces are not showing in the EuControll Settings.
I tried to "Restart Econ Apps", Restart Mac.
I Tried to connect only one Surface.
I tried to connect direct to the iMac ethernet port.
I tried to "Stop" in Econ Preferences and "Start"
I selected the right "Network Interface" in the Econ Preferences.
Nothing works. The Controller are not shown in the EuControll Settings.
:-/
Any Idea?
Thanx
