Hi,
I’ve just downloaded and installed OpenHABian onto a RPi3, all default settings.
I then plugged in my RFXTrx into the USB, and dmesg gives the following output:
[ 2458.316663] usb 1-1.5: new full-speed USB device number 5 using dwc_otg
[ 2458.444158] usb 1-1.5: New USB device found, idVendor=0403, idProduct=6001

[ 2459.502778] usb 1-1.5: FTDI USB Serial Device converter now attached to ttyUSB0
So the hardware seems to be in place. I then proceeded to add the RFXCOM binding via Paper UI. When I then tried to scan for devices, I get a notification in the lower right corner saying “ERROR: undefined - undefined”. So I go have a look in the logs and find this:

I found JD2XX on Github but do I really need to install this manually to make this work? If not, what do I need to do?
