Windows 10 esp-prog libusb_open() failed with LIBUSB_ERROR_NOT_SUPPORTED

#1

I have the debugger working on my windows 11 laptop but it fails on Windows 10.
pio upgrade shows PlatformIO 6.1.6 is currently the newest version available.
Zadig shows WinUSB (v6.1.7600.16385) installed.
platformio.ini shows

[env:az-delivery-devkit-v4]
platform = espressif32
board = az-delivery-devkit-v4
framework = arduino
monitor_speed = 115200
lib_deps = marvinroger/AsyncMqttClient@^0.9.0
debug_tool = esp-prog
debug_init_break = tbreak setup

Builds without errors
but debug console shows:-

Anybody got any ideas?

That doesn’t really matter because it does find the right USB interface afterwards. It tries all matching VID/PIDs and reports this error even if it find the right devic ein the next iteration.

Your real problem is

This usually indicates wrong wiring, debug_speed = .. to high in the platformio.ini or not set, too long / bad cables or power problems. Please try and do everything exactly as Low-cost ESP32 In-circuit Debugging | by Manuel Bl. | Medium.

Thanks Max that article you pointed me to was very usefull. The explanations are great. After double checking everything reducing speed still no joy but I thought I might give it a bit more power using a power adaptor and a hub on the USB line to the ESP32 and that was it. Not enough power. I got stuck on why it would work from my laptop but not the desktop. All good now thanks amillion
