Board COMPLETELY Invisible to Computer

        I just received a bunch of mayfly boards to use and am stuck on getting them to be recognized by any computer. My main machine is a Windows 10. To be clear I mean that the board is not recognized by the system at all – I can’t see it in the device manager “Ports (COM & LPT)” or “Other devices” sections at all. It’s as if the board isn’t even connected. Here’s what I have done:

        Ensure the board is connected via microUSB.
        Ensure the board is on.
        Ensure the power supply switch is set to usb/lipo.
        When plugged in, the LEDs flash green then red continuously.
        I have tried multiple different mayfly boards.
        I have tried multiple different (known to work) USB cables.
        I have ensured that the USB ports work (arduinos are recognized normally on the same ports).
        I have tried plugging into other windows computers, as well as into a mac.

        I’m totally stuck on where to go from here. It’s as if my computer doesn’t even see the mayfly as a connected device. Any help?

          Do you have the FTDI VCP drivers installed? https://www.ftdichip.com/Drivers/CDM/CDM%20v2.12.28%20WHQL%20Certified.zip That’s the chip on the Mayfly that handles the USB communication.

            I discovered it was actually the cable – for some reason the 3 I tried worked with other devices but not with the Mayfly. I tried a fourth and finally the fifth got it to recognize – not exactly sure why the others failed.
