are you using clover or chameleon to boot? Is its synaptic or elan or some other. If its synaptic and if using clover to boot put voodoops2controller.kext in efi/clover/kext/10.10 folder and boot with option of inject kexts in clover boot options. If using chameleon to boot put the same kext in extra/ extensions on the root of your drive,repair permissions!! Should be good to go.
