Hey, So I still can't get this working (v4) on Mountain Lion 10.8.2 and decided to boot verbose and safe mode. There is writing Elan :sucessful or something similar like that.
It actually works on -v -x mode, but not normal mode (without any flags)
I can get to change my trackpad settings from system preferences,
But if without flags, its giving me "connect a bluetooth trackpad"
Please help me so i can use it without any bootflag
