just got the sunfounder starter kit for ESP32 .
plugged module into breadboard and
plugged in power cable. got a red
led on the board came on but computer
did not recognize the board and
download drivers. so downloaded the
drivers manually. that was successful
but Windows still did not recognize
the board. Arduino IDE did not
recognize the board either. Windows
Device manager only shows COM1 and
COM2. don’t know what to do now.

A quick left field question. Is your usb cable both charge and data? A charge only cable could explain your symptoms.
