I can't seem to find a way to unbind the control selections I have made without choosing a key to take it's place. I am using a usb gamepad that only has a single digital pad. I would like to be able to set it to be the analog stick for some games, and the d-pad for other. I seem to now be stuck with the usb controller's d-pad being mapped as both the analog and digital stick at the same time. That works fine for some games that use the d-pad as a mirror for the analog stick, but for games that use the analog stick and d-pad for independent actions the current setup is unworkable. Any advice?
