Hi,
I had a fully working openhab2 setup with RFXcom and MySensors bindings till this morning. (Intel NUC hardware running Ubuntu 16.04)
This morning I disconnected the RFXcom transciever briefly to do some tests with rfxManager on a different PC. After reconnecting the RFXcom device and restarting openhab, openhab seems to have lost the ability to communicate with the serial port of the RFXcom device. The MySensors serial gateway continues to work properly.
Below are the details of the setup. Anyone have any ideas ? How can I further troubleshoot this problem ?
This is Karaf’s log output

The RFXcom device is on /dev/ttyUSB0, this is the RFXcom thing setup

Here’s the output of some commands I used to troubleshoot the problem
$ dmesg | grep tty

$ sudo -u openhab groups

$ ls -al /dev/ttyUSB0

Running sudo cat /dev/ttyUSB0 produces no output, not even when typing Enter or random characters.
I’ve tryed restart the openhab service and even restarted the entire server. Nothing helps.
