How many controllers Clod support?

Hi!
I'm thinking about some DIY controllers based on my old joystick but can't find out how to use more than one stick with CoD. The problem is the same kinda axis of the two controllers. I can't use the second device's axis because it's remapping what I setted up with the first - Two of X,Y,Z axis on the devices but there is only one X,Y,Z in the game. Now I have "two stick" in every plane like schoolplanes...
How is it possible two use the second stick for more axis? (Radiators, Prop, etc.)
