ForcePads do not have any physical buttons, instead they detect click based on finger pressure. Forcepads erroneously report button click if there are 2 or more fingers on the touchpad breaking multifinger gestures. To workaround this start reporting a click only after 4 consecutive single touch packets has been received. Skip these packets in case more contacts appear.
