Synaptics devices reported it has Intertouch support,
and it fails via PS/2 as following logs:
psmouse serio2: Failed to reset mouse on synaptics-pt/serio0
psmouse serio2: Failed to enable mouse on synaptics-pt/serio0
Set these new devices to use SMBus to fix this issue,
then they report SMBus version 3 is using,
patch: https://patchwork.kernel.org/patch/9989547/ enabled SMBus ver 3 and
makes synaptics devices work fine on SMBus mode.
