Iiyama ProLite T1931SAW does not work with Linux - input devices are created but cursor does not move.
It has the infamous 0eef:0001 ID which has been reused for various devices before.
It seems to require export_all_inputs = true. Add it to mt_devices[] as MT_CLS_WIN_8 to fix the problem. Hopefully there are no HID devices using this ID that will break. It should not break non-HID devices (handled by usbtouchscreen).
