I am having the exact same problem, with the exact same board. Windows 8 and OS 10.9… The ActivDriver does not connect, and the board is not listed in ActivManager. On Windows, it sees it as a Human Interface Device and will not use the ActivDriver. It will not calibrate nor am I able to use Dual User mode without it.
