EnOcean binding not working

I have a Leviton WSCOM-W3 that works fine in DolphinView. I have installed the Enocean binding in OpenHAB and set the serial port to COM3 (I am on Windows, obviously).

I see the following line in the logs:
20:13:44.588 INFO o.o.b.e.i.bus.EnoceanBinding[:290] - Connecting to Enocean [serialPort=’/dev/ttyAMA0’ ].

But not the expected follow on:
20:13:45.951 INFO org.enocean.java.ESP3Host[:66] - starting receiveRadio…

Am I doing something wrong? Do I need to have a thing to see this message?
