Can not get Gamecube controller to work with Dolphin.

[Phontsy]

I'm currently using the 3-in-1 Magic Joy Box adapter for my Gamecube controller and I have downloaded the driver from mayflash.com.

According to the configuration under the driver, my gamecube controller is being detected by my PC.

Now when I go to use it in Dolphin, it does not seem to work.

I clicked on the GCpad option and changed the layout to the second option involving the Joy Box, but still nothing.
