Hello, the driver works on an Asus F301A with Elan touchpad. I can turn it off with the Fn key (F9), however if I set "Ignore built-in trackpad when mouse or wireless trackpad is present" unders systemprefs > accessibility the trackpad stays on, I have an usb logitech mouse plugged in.
OSX yosemite, efi clover, driver v 4.2,
