2. if you use MAC OS, you can use python tool to download esp32 firmware. another way, MAC OS also can install plugin for running Windows PC exe file.
3. ONLY download ESP32 firmware by USB-C cable. NOT by RS232.
I think you are misunderstanding the problem: when the USB is plugged in, no device is detected by the computer. THIS IS NOT NORMAL. it is NOT a driver issue - the computer acts as if nothing is connected. I've tried different cables and different computers. Clearly, the unit is *working* because there is activity on the serial port - but the device does NOT show up on the computer in a way that the firmware can be upgraded.
