Issue here on my k4v2, hope someone can help.

Win11, using cable, after first PC boot, the keyboard is not properly connected. It lights up, iirc only num lock light stays on, pressing any key lights it up like start up and again no response. I just pull the cable out of kb and then plug it back in and it works again.

I did the fn+z+j reset, that helped “somewhat”. Sometimes it connects on boot, about 70% of the time, sometimes it doesn’t.

I have been using it since January and had no problems like this. Maybe a recent Win11 update is at fault. Anyone else?
