So it was just sheer luck that it has been working in the past? I find that very unfortunate. Too bad the forum is gone for some more background information. I guess that means I'll have start the bisecting anyway to see what has changed to make it break more consistently now.
I want to use it for a second CEC adapter that isn't even used by Kodi but that causes the other one to break as well.

That would be my opinion, yes.
