Pete mentioned the following, did you check this?
"It could be if you have set your driver policy to "reject unsigned
drivers". I think you can check whether that is the case by following
this post:

And it is also possible that your device is not compatible with
WinUSB. Graeme Gill mentioned that he got one device
not compatible with WinUSB due to buggy get_status
firmware implementation.
