This issue is similar to: Bug 238291, but Acer Aspire V3-371 has no trackpoint. 

Touchpad is not working (at all; cursor is not moving) in Acer Aspire V3-371. I tried various solutions corresponding to synaptics and elantech, but with no effect. 
I can use USB mouse, but no touchpad. 

I have tried patch from https://reviews.freebsd.org/D20507 - no effect, touchpad is dead. 
I also can't see psm0 device. 

When using the same disk on second laptop (Lenovo Y570) I don't observe any issue with touchpad. The same goes for other OSes on Acer Aspire V3-371 (so touchpad is not at fault).

It is SYN1B7F Synaptics touchpad attached through SMBus interface.
FreeBSD does not support such a devices yet.

AFAIK this touchpad should support PS/2 interface too but it looks like it has not been soldered.

FYI, some people are working on it.

> FYI, some people are working on it.

I wouldn't be too optimistic. Such Synaptics devices usually implements Synaptic's proprietery protocol which is not HID-compatible.
