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".
