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).
