[ Upstream commit 32bea35746097985c48cec836d5f557a3b66b60a ]
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.
Hopefully there are no HID devices using this ID that will break. It should not break non-HID devices (handled by usbtouchscreen).
