i have the exact same problem. except ive tried all different types of controllers…… the way to get it to work is to click the controller d4vr- left / right and then click button mapping next to leap motion drop down. although ive run into the issue where sometimes they work, but dont do what i want them to do, but rarely, and unrepeatable, most just dont work at all….. but this way in the config it adds the device, the axis or button, the controller d4vr left or right. so it appears like its all bound. i seriously need some help with this as well, ive been trying for nearly a week.
