Nano rf cannot select port to upload to board

I have purchased 6 nano v3 RF units and none of them seem to get a port assigned to them when I plug them into my windows 10 computer. while they are chinese they came soldered with their pins pushed into foam and each individually boxed so the quality seems to be fairly high. They use the typical micro USB. Is there an adapter like there is for the mini? Is it some other problem? I searched for a while but couldnt find anything related to my circumstance.

Do you see a new device appear in Windows Device Manager after you plug in one of the boards to your computer?

Ended up being a bad cable. Thanks.

I'm glad to hear you found the problem. Thanks for taking the time to post an update. Enjoy!
