espflash fails to automatically set the port #649

Hello! I'm using macOS with a custom esp32s3 board. When I connected the usb cable to the serial JTAG, it shows correctly:

However, I cannot use espflash to access the board without specifying --port:

$ espflash board-info                 
Error: espflash::connection_failed

  × Error while connecting to device

$ ls -l /dev/cu*

The issue occurs on both latest release and git version.

$ espflash -V                                    
espflash 3.1.0

Is your port listed if you use --list-all-ports flag?

By the way, I dont have any issues recognizing a ESP32-S3-DevKitC-1 v1.0 connected via USB Serial JTAG port.

$ espflash -V

No, still

$ espflash board-info --list-all-ports

Have you tried with other flashing tools like esptool?

I just tried esptool:

pip install esptool
esptool.py flash_id

It recognizes the chip

$ esptool.py flash_id
