E5520 Trackpad not working

Hi I have the Dell Latitude E5520, with the sepcs

Processor: i3-2350M 2.30GHz

RAM: 6.0GB

SSD:240GB

Touchpad: ALPS Dell Touchpad

OS: Yosemite 10.10.1 Hackintosh Zone

 

I can't seem to get my trackpad working, and the funny thing is, it one day just randomly worked and hasn't worked since. I use the kext from here https://osxlatitude.com/index.php?/topic/2545-new-touchpad-driver-for-e6520-alps/page-25.

Does anyone know how to get it working. Also with the mousepad kext I installed using kext wizard and copied the daemon to usr/bin.

Looks like you're using a non vanilla install method. Check your system for other PS2 kext that might have been installed.

Look for ApplePS2Controller, AppleACPIPS2Nub, and VoodooPS2Controller. Remove them and then just re-add the one linked earlier. Repair permission and rebuild cache.

I removed all of those kext, and it still didn't work. Could it be due to me using the Hackintosh.zone version, is there a different method that could guarantee more success? I also haven't tried patching a DSDT yet if that help, I only have the vanilla DSDT saved on a harddrive.

Don't need DSDT for mouse to work. Are you currently using an external mouse?

Go to preferences and see if trackpad is detected.

Also check to see if the kext is loaded by going in the terminal and run

kextstat | grep VoodooPS2
