Firstly it's important users get the correct messages about hardware
problems and don't just assume Linux sucks. Secondly at least some of
the capture drivers do the right thing and fall back to other methods.
Those that don't I intend to take up further because the default
behaviour should be the safe behaviour.
And "all that code" is a single quirk (which I think can be __init as
you can't get a hotplug bridge) and updated logic checks which my gcc
generates the same amount of code for as it did previously.
All what code ?
