if non-intrusive probing is definit for all possible devices, then you
have exact results. Or if you have only one intrusive driver (which is
left to the end of the probing). More intrusive drivers lead to indefinit
results.

[ i'm talking about theoretically indefinit results, it usually works
fine, but you cant be sure unless you discover the whole probing space
which is usually impossible ]

if the non-intrusive probing is not definit enough, then we are in
trouble. (ie. if you can detect two devices on the same port). But this is
quite rare. [report it if it happens and it gets fixed]. You can think of
the mechanism that Linux device driver writers do as an "informal but
quite well-working probing-order database".
