Description TJ 2016-05-03 22:22:42 UTC

The ELAN 3320KD-3100 multi-touch controller chip is a 64-pin QFD package. In the Asus T300CHI it is behind a BCM20730-A1KFBG Bluetooth radio controller in a detachable keyboard/trackpad dock. 

It identifies with the Asus ID 0B05:8502.

It works as a mouse but there is no scroll or gesture support.

I have this issue too with my t300chi. I am keen to resolve issue and would gladly help. Am using 16.04 with kernel 4.10.32?  As provided in updates. Can post documentation if helpful.
