It does work, it connects and installs the HID profile, and also shows in the Game Controllers list. However, like I already said, GlovePIE won't read the inputs until I enable the "Bluetooth Fix" option. Everything works fine then, LEDs, rumble, buttons, motion and IR all work within the GlovePIE scripts.
So what i'm saying is the same reason that GlovePIE cannot read it without the fix enabled is probably the same reason Wiisis can't.
I've tried both the microsoft stack and widcomm, same thing happens on both. It seems to be quite a common problem for Vista users from what i've read.
