Hello.The Steam Controller with the open fimware could be seen as a Switch Pro Controller which could be connected usb.
My question is if the code than Steam use for connect wireless with the usb wireless device/Steam Link could be used with the Switch Pro controller for allow use it wireless.
I know than the usb should be modded with other Pid,vid,.. but with the great sys-con atmosphere module it should no be difficult:
