Hi,
I recently purchased two feather nrf52840 boards through digikey (purchased June 25) and for seemingly no reason they are connecting sporadically, and as of this morning one is no longer recognized by my PC. Up until this morning everything was working as expected, except that after flashing a new sketch the board would occasionally stop being recognized. Now the computer no longer sees the board as a COM device and instead lists it as an "Unknown USB device." I have tried...different cables, different USB ports, resetting the board with the reset button, re-installing the Arduino IDE/drivers, rebooting my computer and no luck. A different, previously purchased feather nrf52832 still works fine, so I don't think it's a problem with my computer.
What should my next steps be?
Thanks so much,
Melanie

Sorry for delayed response. It sounds like they were working originally and then:
