Ah, that makes sense. It works for me now too :)

Thank you (and everyone else) for your help! I will inform my professor and
hope that he includes the changes so other students doesn't have to run into
the same problems as I did.

I guess this bug can be closed then? As you said, the order of the returned
configs doesn't have to be in any specific order. So I guess the other drivers
just got lucky.
