Host is an Asus notebook (N-series) with Windows 8.1. Two-finger gestures are enabled (ASUS "Smart Gestures").
Guest OSes, on latest VMware Player are: Windows 10 Preview, and Linux Mint 17.
In both guest OSes I couldn't get two-finger scroll working so far.
The ASUS touchpad in system devices, on Host OS, is just described as "ASUS Touchpad", duh.
I also tried the "Two-Finger Scroll" application on Host two-finger-scroll - Two finger gestures for Synaptics TouchPads on Windows - Google Project Hosting
but it gives an error: interface not registered.
