So this is largely a case of the kernel driver not setting the right bits, and udev then not labelling it correctly for us to pick it up. Look at the evtest output:įor a device to be detected and labelled as touch device, it should have BTN_TOUCH (see systemd/src/udev/udev-builtin-input_id.c). That again is because the tablet itself doesn't seem to be correct. It should have ID_INPUT_MOUSE or similar for the server to pick up on it. The reason it's not assigned any driver is because the ID_INPUT_* keys are missing. Optical Wheel Mouseīus 004 Device 002: ID 6615:0070 IRTOUCHSYSTEMS Co.
