kensington expert mouse setup

i currently have a nano4 with expert mouse directly plugged into it...
i thought since it was "native" it would respond like hog trackball control...
i can only get a regular mouse function off this thing...

i still have no pan/tilt control and no button functions :(
what am i missing...or is it not fully supported for pan/tilt control?

any help is greatly appreciated
thanks!
