I can confirm that this bug manifests on my Asus G552VW as well. With the 4.2.0-30-generic kernel, the ELAN1000:00 trackpad is not recognized as a trackpad and gets treated as a "evdev pointer catchall" by X.
I also tried last week's 4.4 and 4.5 kernels. Both of them resulted in a non-functional trackpad. With those kernels, elan_i2c recognizes the device as i2c-ELAN1000:00. With those kernels, syslog fills with messages like the following every time I touch the touchpad, and the touchpad is otherwise unresponsive.
