Post the rest of your code
At this point it could be WMI fudging up or it could be the loop you use to go through all of the items!

    I don't think it's the loop, but here's the code:

    My guess is I'm missing some bus relations which I can't retrieve with "Win32_Bus". (The IDs I get with this call are not unique, hence I cann't use it).

    Am I missing something in this query?

    Update: Guess I'm looking for a logical bus, not a phisical one. But were (and how) to find it...?


    Update:
    Win32_Bus retrieves the phisical Bus devices. This is not the thing I needed, since more devices are connected on 1 physical bus.
    I did found a solution however.
    I have to querry the PDO (Physical Device Object). These can give me enough date (along with the deviceID) to combine all instances, created by the drivers, that belong to a single device.
