[ Upstream commit fb68ada81e65d593b51544fa43c284322107a742 ]

The Trust Panora Graphic Tablet has two interfaces. Interface zero reports pen
movement, pen pressure and pen buttons. Interface one reports tablet buttons
and tablet scroll. Both use the mouse protocol.

Without these quirks, libinput gets confused about what device it talks to.

For completeness, here is the usbhid-dump:
