this is correct, but it is _the_ standard way of doing it 
since..hmm...kernel-2.6.8 i think.
and prior to this there was devfs, which provided the same functionality 
(kind of).

i would really suggest to _not_ probe each device whether it is actually 
valid, but instead to rely on a properly set up /dev-tree (either 
manually or via udev or similar).

blind probing is likely to hang your system.

getting the available devices (and making them accessible) is really a 
task of the operating system and not of any application.
