alexboiboule This is a common problem that you should be able to resolve with a little Google troubleshooting imho. Try googling 'usb3 reports usb2 with windows 11' and you'll get info like;
A USB 3.0 port can report as USB 2.0 due to a poor physical connection, an issue with the cable or port, or outdated/corrupt drivers. To fix this, try plugging the device into a different port, reseating the cable, or using a different cable altogether. You should also check the Device Manager to ensure the correct USB 3.0 drivers are installed and update them if necessary.
My Q3 with official link cable continues to work fine with latest win11 updates btw.
