4 wii controller with Mario Kart not possible?!?!

[satrocker]

I have a Problem when i want to use 4 Wii controllers at Mario Kart. I have a Gembird Bluetooth Dongle. (i tested a other to)
When i start Dolphin all 4 Controllers are shown. But when i play Mario Kart, and take the option 4 Players, its only possible to activate 3 Controller. I connected and disconnected the 4th Controller (with the Tool Menü) but no function. Is this a bug or is there a Trick to use 4 Controllers?
I use the newest Dolphin Version on Windows 7 64 bit.

Nobody who can help???
With 3 Controllers does it run.
But not with 4.
When i take 4, it disconnect himself everytime.

a simple forum search will reveal this is a common problem with dolphin. try an older version like 6515. i havent tested myself but ive heard others saying this problem started with a revision in the 72xx i think
