esp32S3 The USB function is occupied by USB jtag/serial (VID_303A&PID_1001)

openby absn12opened 2025-06-27updated 2026-03-12

Port, board and/or hardware

esp32S3

MicroPython version

MicroPython v1.24.1

Reproduction

No, I've provided everything above.

Expected behaviour

Like 1.19, there is no need to plug or unplug the USB cable, and USB related functions can be used normally

Observed behaviour

on win10
After connecting the USB cable and booting up, the pc system will generate a USB jtag port. After entering micropython, all USBs do not work (such as my microPython USB CDC repl), and the USB jtag port will continue to exist (not work,VID_303A&PID_1001). Only by plugging and unplugging the USB cable once can the relevant USB functions work properly
V1.19 does not have this issue (but on 1.19, IDF's bootloder performs some pin detection to enter different OTA apps. detection stays for >200ms, the same issue will also occur)

Additional Information

No, I've provided everything above.

ESP32S3

MicroPython version

1.23 / 1.24

Reproduction

Instll kernel, reset, see if it boots

Expected behaviour

Boots

Observed behaviour

Loading firmware 1.24 does not boot using USB-OTG. I don't have serial port. Just USB-OTG, so need kernel to default that on.

Loading firmware 1.23 works as expected.

Additional Information

No, I've provided everything above.
