Hi,
On my HP Zenbook I got:

[Tue Aug 28 17:11:52 2018] psmouse serio3: synaptics: Your touchpad (PNP: SYN300a SYN0100 SYN0002
PNP0f13) says it can support a different bus. If i2c-hid and hid-rmi are not used, you might want to
try setting psmouse.synaptics_intertouch to 1 and report this to linux-input@xxxxxxxxxxxxxxx.
After booting with psmouse.synaptics_intertouch=1:

And the touchpad still works fine. So I guess RMI bus should be used by default.
Thanks for the report. Just to double check, is the touchpad still
working after suspend/resume?
Yes, just tested that. The tp still works after a suspend to RAM cycle.
If so, we can definitively add a patch to add this device to the list
of properly supported over SMBus touchpads.
Thanks,
Ortwin
