I built one of TallDog's 3.5 Due breakout kits. I've done two others that work fine.
This one is not getting recognized by my computer. When I plug it in, the computer chirps as expected, but Arduino doesn't see it and nothing gets added in Device Manager under Human Interface Devices. In Universal Serial Bus Controllers, I see "Unknown USB Device (Device Descriptor Request failed)."
Hopefully this can be fixed.
ny ideas on where to look?
