Is what you described really a misconfiguration? Enabling debug when
something does not work seems obvious thing to do, but okay, perhaps
anything bellow error level would make me happy enough.

As a side note, which efforts are you reffering to here?

tty and usb for example. I do not consider wise to looking at them until
this very subsystem gets fixed first to not distract ourselves ;-)
(Also I have admit, that accepted patches hide error message on deferred
probe only, but above occurs _also_ on deferred probe and yes, it would be
nice to have that fixed)
