Comment 88 for bug 1166442

This works! Ubuntu with kernel 3.9.6. Thanks kendatsuba for the patch and G.Scoppino for the compile instructions.

I did however get a error when running make install. Seems for me that everything works, but I do feel that I have a more unprecise movement of the pointer when I am moving slowly. This is the error after running sudo make install:

run-parts: executing /etc/kernel/postinst.d/dkms 3.9.6 /boot/vmlinuz-3.9.6
Traceback (most recent call last):
  File "/usr/share/apport/package-hooks/dkms_packages.py", line 22, in <module>
    import apport
ImportError: No module named apport
Error! Bad return status for module build on kernel: 3.9.6 (x86_64)
Consult /var/lib/dkms/psmouse/elantech-v6/build/make.log for more information.

And in the make.log file I get this:
