Hi Piet,

Have you set the `EXTRA_JAVA_OPTS`, as described [here](https://community.openhab.org/t/setting-the-extra-java-opts-on-oh2/24061)? I’d also advice to use symlinks to give your USB device a meaningful and constant name, as described [here](https://community.openhab.org/t/raspberry-pi-make-serial-usb-ports-persistent-via-symlinks/35847).

Good luck!  
Bart
