Probably some are not relevant for the Touch controllers, e. g. IndexTouch, but even then the spilled warning every second are an annoyance. More importantly, the effect is that touchpad events cannot be resolved. The following sample (closed issue #65) does not work:

if (ViveInput.GetPress(HandRole.RightHand, ControllerButton.PadTouch))
{
    Debug.Log("padAxis = " + ViveInput.GetPadAxisEx(HandRole.RightHand));
}

And I can confirm this is not due to potentially just missing "user presence" on the Oculus, i.e. HMD is not put on the head. Axis values remain (0, 0).
