I have a variety of ESP32 & ESP822 Firebeetle boards with micro usb connectors that are discovered correctly . The Mac only has USB C connectors.
The Firebeetle ESP32-E board with USB C connector is not seen by serial-discovery , though the MacOS detects and lists the serial connection correctly.
I have used the technique of running serial-discovery directly . version 1.4.1
In SYNC mode it correctly detects the insertion and removal of all the boards except the ESP32-E
The Mac detects this board's USB serial as:
USB 3.1 Bus:
Host Controller Driver: AppleT8122USBXHCI
USB Serial:
Product ID: 0x7522
Vendor ID: 0x1a86
Version: 2.64
Speed: Up to 12 Mb/s
Location ID: 0x01100000 / 1
Current Available (mA): 500
Extra Operating Current (mA): 0
Many Thanks
