Yeah, it's f25. So that's interesting, but it's not the mouse device
(because I don't have one). I suspect you're right about the cause,
though. I'll poke hughsie about it, thanks.
Right, mouse is BT, so you can only get to btusb locally, that's what I see
too, just a bit misworded since it was awhile ago and my memory is a bit hazy.

I'm not sure how to take to this statement. Are you really chiding me
for using the version that's in the distro I'm using?
Oh, no. Just a comment that current powertop handles this better and
once Fedora catches up you'll see the benefits too.
