I just updated my XKEY AIR 37 and WIDI BUD…using windows 10.
You mean you updated both firmware of WidiBud and Xkey, and the issue appeared after those firmware updates ?
Did you try to remove the Xkey from your known devices and connect it again ?
Also, can you see an error code somewhere in addition to ‘Driver Error’ ?
