The Chalkboard Electronics HID Touchscreen is classified as a tablet device by systemd udev because it has BTN_TOOL_PEN support. It also reports a resolution of 0 for both X and Y axes in absinfo. This causes libinput to reject it as an invalid tablet device.
This quirk reclassifies the device as a touchscreen which allows it to be added as a valid input device.
