Location of serial console port not constant (with ESP32 USB connections)

[dx136]

PROBLEM DESCRIPTION

A clear and concise description of what the problem is.

On an ESP32 device (i.e. ESP32-S3-Zero), the location of the serial console port is not constant. Perhaps this is by design but not what I expected (or perhaps I have misunderstood the meaning & purpose of "Serial Tx/Rx" in the template?)

Scenario: GPIO pins are defined for Serial Tx/Rx (i.e. 43, 44); they work correctly (i.e. allow console commands to be issued) when the module is powered from a simple USB power block (i.e. no USB data connection). When the device is powered from a laptop and a USB data connection exists, the GPIO serial pins no longer respond; instead, console commands can only be issued from the USB serial device (e.g. /dev/ttyACM0). Thus the location of the console port is not constant.

Preferred solution: Provide a (new?) command that sets the location of the console port. This command could be used from either the webUI console or used in a rule with system#boot.

Thanks very much!

TO REPRODUCE

Steps to reproduce the behavior:
[Copied from Problem Description] Scenario: GPIO pins are defined for Serial Tx/Rx (i.e. 43, 44); they work correctly (i.e. allow console commands to be issued) when the module is powered from a simple USB power block (i.e. no USB data connection). When the device is powered from a laptop and a USB data connection exists, the GPIO serial pins no longer respond; instead, console commands can only be issued from the USB serial device (e.g. /dev/ttyACM0). Thus the location of the console port is not constant.

EXPECTED BEHAVIOUR

A clear and concise description of what you expected to happen.
[Copied from Problem Description] Preferred solution: Provide a (new?) command that sets the location of the console port. This command could be used from either the webUI console or used in a rule with system#boot.

Alternative 1: a (new) command which allows the relative priority of the serial Tx/Rx console vs the USB console (right now, USB console has priority and overrides the serial Tx/Rx).

Alternative 2: a #define directive which sets the relative priority of serial Tx/Rx console to be higher than USB console.
