Thank you for the reply. On windows 10 I had the version 2 Beta and version 1.8.16; both worked without incident. Neither are able to see devices I plug into USB ports on Win 11.
Device manager looks like this:
COM1 is the old serial port.
This is what I see in Arduino:
This is the ESP32 Devkit v1
I have no idea which chip it uses, Cp210 or WCH CH340. Are you able to tell from the photo?
I have installed CP210x 64bit drivers on Win11. But not the CP210x drivers.
It doesn't make any difference to which USB port I plug into, neither Windows or Arduino react to it. In the motherboard (MSI B550M PRO-CDH WiFi AM4) BIOS I have USB XHCI hand off disabled and Legacy set to Auto.
Regards,
Dicky.
