Which exact build did you flash on your fusion? This information should be available on the system info page of the dtu.

I think you should use the esp32s3_usb build instead

[schlimmchen]

Yes, as is documented.

@onehub278 You may use the esp32s3 variant (without _usb), but you can't expect to see message output on the USB port in that case. The messages will appear on the UART header instead.

I got a openDTU-development branch in Platformio on Visual Code. There an enviroment openfusionenv2 is available. Is this outdated or a new feature?

[schlimmchen]

Neither. It's the same as generic_esp32s3_usb, except that it defines default values for some pins, which you can as well set using the recommended method: uploading a pin_mapping.json.
