Comment 13 for bug 1670492

Thanks @anthonywong! I can confirm that after installing oem-touchpad-psmouse-1615937-dkms_1.0sutton1_all.deb package the middle button is detected in my E470 and Trackpad scrolling works now like any standard mouse wheel scroll.

I'm currently running 16.04.3 LTS (Neon 5.8 actually). Here's the xinput output after installing this DKMS package:
