Unity does not recognize controllers in the right order, or mixes them up

Hi there!

I'm working on a game where there are multiple xBox360 controllers attached to the pc. The problem is that, seemingly randomly, Unity recognizes part of the Input from one controller as Input from the other and vice versa.

Has anyone else encoutered this problem and has some fixes? I've seen an alternative posted here before, but it only works for windows, I plan on making the game for cross platform...

Thanks a lot in advance!
