Hello, there is no need to run the program as administrator. First thing you can check is that COM7 is the correct serial port for your screen. If not, you can replace "AUTO" here https://github.com/mathoudebine/turing-smart-screen-python/blob/main/simple-program.py#L19 by the correct COM port in case the auto-discovery failed. Second thing you can check is that the vendor program UsbMonitor.exe is not running in background.

Thanks for the reply. I've tried manually setting the com port, i also tried changing the com port. UsbMonitor isn't running either.

I have the same issue. No other programm uses the COM port. Changing the COM port, for example to COM6, does not help. I've tried changing from auto-discovery to a fixed COM port, but issue is the same.

I ended up using Sim Hub as an alternative

Hi @moldark-debug There is indeed a bug in auto-discovery, but if you set the COM port manually it should have been running fine Can you send the complete log when you run the program? Are you sure you entered the correct COM port for the screen in config.yaml file?

I entered the correct COM port in the config.yaml file and get the same error:

Make sure UsbMonitor isn't running.
