I try different VoodooPS2Controller only 1Revenger1 and Dr. Hurt work only click and touch. So I find this config, take from there VoodooPS2Controller and add to config.plist.






Now is working, thanks for help






one more thing, when you copy all kext connected to Voodoo2C after sleep it will crash, so better stash them it this case

As far as I know, this model does not have I2C touchpad, so not sure why you would try to add them.

The attached Config has ApplePS2SmartTouchPad.kext, not VoodooPS2Controller, so I'm confuse. Which kext+plugins work for you?
