Hi there,
I could confirm, the Seeeduino Nano don’t work under W11/Arduino IDE 2.1.0. I received a new PC with W11 recently so I needed to reinstall everything and copy all of my backup’d files back. I used the same Nano board under W10/Arduino IDE 2.1.0 with no issue. However I use in more projects the Nano boards, so I needed to resolve this issue and the solution? Simply I installed the latest old version of Arduino IDE of v1.8.19 which seems paired with a proper Seeeduino USB driver, BUT it’s works with the old Arduino IDE only!
