I'm able to connect a Wiimote to WiinUSoft and it will recognize an attached Classic Controller. However, a few seconds (varies from about instantly to 10 seconds) after I connect it as an Xbox controller, the background for the connected Wiimote will turn red (as though the battery is low, but my Wii puts it at 3 bars consistently right now), and about 3 seconds later, the Wiimote will disconnect and turn off. I thought it was related to Windows installing bad drivers, but I disabled automatic driver installation and the issue persisted.
Some more work with this has led me to conclude that, in fact, Windows device setup is playing a role in this issue. What I disabled did not stop Windows from performing device setup, it just stopped Windows from downloading new drivers automatically. Does anyone know how to keep Windows from trying to set up a device?
I think, if I were just able to make Windows 10 not try to set up the Wii remote, it would work perfectly fine. But I have no idea how to do that, and I'm having trouble finding anything similar on Google.
Oh, are you using the Windows Bluetooth to connect the controller (like you would any other device) or are you using the sync button in WiinUSoft? Also, if all else fails you can try going the Toshiba BT Stack route.
