random board name appended to Arduino Port menu listing

Board

AI-Thinker (NodeMCU) ESP32-C3-01M-KIT

Device Description

ESP32-C3 board (not in list), using "ESP32C3 Dev Module" board name.

Hardware Configuration

Using internal USB IO18, IO19

Version

v2.0.4

IDE Name

Arduino IDE 2.0.0-rc8 (same behavior with 1.8.19)

Operating System

MacOS Catalina

Flash frequency

40 mhs

PSRAM enabled

no

Upload speed

115200

Description

The Port Select Menu lists: /dev/cu.wchusbserial1410 (some board name)

The board name randomly changes when resetting board, this causes the no board selection, have to re-select current name displayed in menu to reactivate port. The current port menu title lists just the port name: "/dev/cu.wchusbserial1410"

This change in behavior started some time in September, I assume an Arduino or espressif board plugin update introduced the new behavior.

In a dozen resets I might see a variation of port names like:
/dev/cu.wchusbserial1410 (ESP32S3 Dev Module)
/dev/cu.wchusbserial1410 (AirM2M-Core-ESP32C3)
/dev/cu.wchusbserial1410 (ESP32-S3-Box)
/dev/cu.wchusbserial1410 (Adafruit QT PY ESP32-C3)
/dev/cu.wchusbserial1410 (LOLIN C3 Mini)
/dev/cu.wchusbserial1410 (DFRobot BeetleESP32-C3)

Actually using: ESP32 by espressif 2.0.5

Debug Message

Compile/Upload result after reset changed port menu listing:

Failed uploading: no upload port provided

Other Steps to Reproduce

FYI using ESP32-C3 micro-USB connection, I get 2 port choices:

/dev/cu.wchusbserial1410 which works for code uploads.

/dev/cu.usbserial1410 which works for serial monitoring

(I might have 2 CH340 drivers installed?)

Also found patching boards.txt entries to TRUE helps serial monitoring work

esp32c3.serial.disableDTR=true
esp32c3.serial.disableRTS=true

I have checked existing issues, online documentation and the Troubleshooting Guide

Because the USB PID and VID of our boards are the same, the IDE can not differentiate which board is connected and usually shows the first one that matches VID/PID. This is not something that we can fix.

As for serial.disableDTR/RTS values, those might depend on the USB UART chip and/or EN/BOOT setup of the board.
