Enocean caused a problem

I run a virtual box with Openhab2.
I installed Enocean Binding.
I have the 300 USB Stick.

dimes shows it connected to dev/ttyUSB0

Openhab Log:
10:30:01.978 [ERROR] [org.apache.felix.configadmin ] - [org.osgi.service.event.EventHandler, org.osgi.service.cm.ManagedService, id=298, bundle=188/mvn:org.openhab.binding/org.openhab.binding.enocean/1.9.0]: Updating property serialPort of configuration org.openhab.enocean caused a problem: Serial port ‘/dev/ttyUSB0’ could not be opened. Available ports are:
