i dont know much about it… but apparently according to this document
the ESP32C3 internal chip pins 25 & 26 are connected on the board to GPIO 18 & 19 which is USB D- and USB D+
so i think you have to use the usb cable connected to these pins to access IIS
seems like i read something about this somewhere else i will try to see if i can find a reference
