Arduino Due mouse simulation on Windows CE 5.0

I'm trying to use the Arduino Due and simulate a mouse (using the native port).
when I'm connecting the Arduino to a Windows CE system, the system doesn't recognize the input as a mouse and doesn't use the generic mouse driver (the system ask for the driver's name).
on any other OS I've checked, Windows recognize the Arduino as a generic HID mouse.

Anyone got a solution or a Windows CE driver?
