Comment 0 for bug 1777679

Laptop is an Asus-GL503VD

Touchpad is an ELAN touchpad model 1200.

This bug is relative to the Asus-GL503VD and any Asus laptop using the ELAN1200 touchpad.

I tried Arch, Debian, Ubuntu 14/16/18, Pop_OS, Sabayon Linux, Fedora. Same problem, touchpad is totally unresponsive.

From what I understand the touchpad is being recognized as a keyboard and I cannot get any driver to recognize it: elan-i2c or synaptics.

The touchpad is also being recognized as a USB device.

This behaviour was consistent on kernels 4.15.0-22, 4.15.0-23 and 4.17.1.
Right now trying to make it work on kernel 4.15.0-23 because it seems more "main-stream".

Note: I have a keyboard recognized as AT Translated Set 2 keyboard which makes me believe I do not need ITE8910 to be a keyboard.

Note2: Been researching LKM development. Managed to make a signed 'hello world' lkm and make it output in dmesg. Willing to help debug/develop the driver for this touchpad.
