I have been looking for the best way to connect the Wiimotes( I have 2), and the easiest way is with bluesoleil! I have tried the broadcom, microsoft stacks. I think bluesoleil is the easiest. I downloaded a couple of autoconnects for the Wiimotes but could not get them to work using vista 64. I'm also using smoothboard for the Wiimotes, it's a better program.
If you dongle doesn't come with bluesoleil , then you have to buy it!
