Hi everyone,

Windows 11 detects my ESP32-S3 as an unknown device.
The board uses a CH340X USB-to-serial chip.

I’ve tried different USB cables and ports, but the issue remains.

Driver issue maybe?

Thank you for your reply.
I tried what you suggested, but unfortunately it didn’t solve the problem for me.

Power supply issue maybe? Where does the +3V3 come from? Anything else in the circuit which may draw too much power from VBUS?

Did you reboot after the driver install ?
Just curious why you didn't just use the USB pins on the ESP32-S3 and avoid the CH340x all together.

There would also be a display and a motor connected, but they are not hooked up at the moment.

Yes I did, but not working
