The Logitech Casa Touchpad does not reliably send touch release signals when communicating through the Logitech Bolt wireless-to-USB receiver. Adjusting the device class to add MT_QUIRK_NOT_SEEN_MEANS_UP to make sure that no touches become stuck, MT_QUIRK_FORCE_MULTI_INPUT is not needed, but harmless. Linux does not have information on which devices are connected to the Bolt receiver, so we have to enable this for the entire device.
