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?

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?
