I installed VoodooPS2Controller.kext but my touchpad don't work as expected. Pref panel shows "No trackpad found". Basically its detected as mouse

I tried a lot of options but none of them works.

It is because your trackpad is ELAN and the PS2 kext you're using has no direct support for ELAN as trackpad.

You can search for an ELAN specific PS2 kext and use that or you can use SSDT-MouseAsTrackpad.aml (.dsl in VoodooPS2Controller github) to make VoodooPS2Mouse simulate a trackpad (not all trackpad features work, but some do).
