Hi, Nikolaus,

Your Touchpad is 044E:120C, right?

PATCH 1/2 supports 044E:120C Touchpad device.
I think you can use all features of this Touchpad.

PATCH 2/2 supports 044E:1215 Touchpad device.
You don't need to care about this.

If Touchpad does not work completely, there is something an error.
What does dmesg show?

Best Regards,
Masaki Ota

I tried your patch on an HP Elitebook, but with rather limited success. Before, I was able to use the touchpad in limited fashion (https://bugs.freedesktop.org/show_bug.cgi?id=100345). With your patch (applied on top of 4.10), the touchpad no longer reacts at all.

That said, I didn't find a patch 2/2 anywhere.. is there something missing?

Thanks,
-Nikolaus
