AlpsHID

This is a satellite kext which uses VoodooI2C's multitouch engine to bring native multitouch to the Alps touchpad using the HID protocol. Trackpoint(StickPointer) is supported aswell, including the buttons.

Installation Considerations

Should work when injected via Clover or OC, but you do need VoodooI2C / VoodooI2CHID. Use the supplied VoodooI2CHID as it contains a fix not yet implemented in the main version.
