Not worked here. Maybe because is a 3th party clasic controllerWiiSXR already has Classic Controller support, you just need to launch vWii mode first, sync the controller there, then use vWii HBC to launch WiiSXR.
No idea about Not64 controller support.
There were a WiiSX version working with a PS3 USB controller too, I don't know if it's implemented in WiiSXR. I'm trying to find it, maybe I dreamed...
PS:
I updated this thread's first post with links and changelogs, it looks better now
