ok, i did some more test.
First, on a real system and not in a vm.
Second, with 2 different bluetooth dongles.
What i did find, is that it works, till the orbiter pops up a new bluetooth device found and proposes 3 different devices, one phone and 2 other devices.
The only choice you have here is ignore for now or ignore for ever.
After this screen, the WiiRemote stops working
