New MKR1310 not detected by W10 PC

I bought an MKR1310 months ago and just decided to open it up and try it this week. I have three micro USB cables that I have confirmed transmit data with a smartphone, but none of them allow the MKR1310 to be detected. I get the green "ON" LED, but neither Windows Device Manager or the Arduino IDE detect the device when plugged in. It's never been connected to anything else and I removed the shipping foam before powering on. I've installed the SAMD module in the board manager.

Any ideas? Do I have a dud board and didn't find out until now? The only post I found said they had a bad USB cable but I've tested that.

Thank you in advance,
Dylan

hey Dylan did you ever get your '1310 to work? If so, how? I'm having a similar problem
