Ok, I've found it. It's the one marked BIOS. The damned thing is that even if I disable it, it will "find it", again and again. When I check Aida64 it is found as "No device connected". So it's obviously a ghost-driver or whatever they call these things. I had to disable the sound for that event to none, and deny explorer from giving notifications. That way there's no visual or audible warnings, which is ok, as I don't actually need to be warned if I connect and re-connect the mouse or whatever, and if something doesn't work, I can easily enough open Device Manager and check.
