Hi
Situation is Win11 PC running Arduino 2. Device LOLIN (WeeMos) D0, R1. or any generic ESP2866 device.
CH340 driver installed and seen in Device Manager.
Device recognised by any selected port (in device manager).
BUT
IDE reports "Port not found" in serial monitor or programming mode.
Serial on a terminal is OK.
AND
Device works OK on a Win 10 PC running same CH340 driver.
To maintain my sanity any pointers gratefully received.
Cheers
