Serial port does not exist

Setup, Configuration and Use Installation
#1

I have some issues with connecting a USB device to my setup.
I’ve a brand new openhabian installation and configured both options in 35 (Serial Port setup).

lusb gives me the device

Bus 001 Device 007: ID 0403:6001 Future Technology Devices International, Ltd FT232 Serial (UART) IC

sudo ls -l /dev/ttyUSB0

crw-rw---- 1 root dialout 188, 0 Dec 22 14:37 /dev/ttyUSB0

But the binding I use (DSMR Binding) keeps complaining that the serial port does not exist. Also tried it with the Serial Binding

dmesg | grep tty also gives no errors:

usb 1-1.5: FTDI USB Serial Device converter now attached to ttyUSB0

What am I missing?

#2

Is the user that is running OH a member of the dialout group? You can run the id command and it will tell you what groups the user belongs to.

#3

yes it is:
