Acer E5-573G Touchpad

Sorry for my english, гm italian. I have в problem with Linux on my laptop: the touchpad doesn't work. This is the "xinput" output:

Virtual core pointer                        id=2    [master pointer  (3)]

"SYN1B81:01 06CB:2970 UNKNOWN" is the touchpad, and this is the output of "xinput-list - long 12":

SYN1B81:01 06CB:2970 UNKNOWN                id=12   [slave  pointer  (2)]

Then I tried "xinput enable 12", but it didn't work. The touchpad works without problems when I boot from the Windows 10 install disk.

Thanks in advance and sorry, again, for my english.
