--- Comment #10 from Zoltán Böszörményi <zboszor at pr.hu> ---
I have a kernel patch based on parts of the GPL EETI kernel driver
I got sent to by way of a PC maker. The patch is at:

http://marc.info/?l=linux-input&m=150167441312020&w=2

With this patch, xf86-input-libinput works out of the box.

The way EETI treats their devices is somewhat funny.

Their kernel driver leaves a backdoor (a pipe) so the older generation of their
closed source daemon can switch it into some specific mode. Then the daemon
opens a new uinput device and feeds it with data.

Same with their latest generation of said daemon which talks to the device
over a hidraw device node. The in-kernel hid-multitouch driver then completely
loses events and only the events fed by the daemon to uinput is accepted.
