I have the exact same problem, did you get it fixed? I was able to get a screenshot of the Devices and Printers Window icon that shows up for less than a second when I plug it in, see the attachment.
There is no port created in Device Manager like for other Arduinos.
I am running Win10 64 bit professional.
Another test I made was to apply 7V btwn the Vin pin and GND pin, then insert the usb connector. In this case windows did not respond at all, nothing happened at all when I plugged it in. I also tried a 2nd cable and other usb ports. I'm about to throw it in the trash.
