I've just get a new laptop: ASUS Zenbook ProUX501UW FY102T and after installing Gentoo the touchpad is not recognized. I've spent days googling and test a LOT of solutions but nothing worked.

What I've tried:

- test kernel from 4.3 to 4.9 (from official github this one)
- tried tons of parameters into kernel boot like noloop, nopnp, nomux, reset etc..
- installing synaptics, evdev, libinput
- Live CD ubuntu 14, 15 (16 freeze at the boot), latest fedora, arch linux: no one get a working touchpad
- compile the whole list of i2c drivers and load them as modules or in-built

It seems a lot of people got/is getting this problem, some patches have been pushed into the kernel to solve their problem but nothing worked for my case.

Here the important information:
