Trackpad not working t440p Catalina

[PaoloJC]

Hi guys, this is my first post on this forum. that helped me a lot building my first hackintosh on my Lenovo t440p. everything seems to work, except from the wireless/bt (for the moment, I'm using an USB adapter), and the trackpad. When I was installing it, it worked nicely, but afterwards, only right click and two finger scroll works, no gestures... I'm currently using an usb mouse that works well, by the way.
I don't know what to do, except to ask for your help guys! I don't know what to attach, I've tried with some kext (VoodooPS2Controller, VoodooHDA) I don't want to install something that will make my hackintosh unusable, so can you tell me which kext I have to install?
I hope that you can help me guys, thank you in advance!
