Gemma v2 not recognized by computer

by lorennason on Sun Jun 04, 2017 8:52 pm

I bought 2 Gemma's
One works
one does not

On the one does not work:
I don't get a dim 'red' LED. I don't get a flashing/blinking 'red' LED for bootloader.

I get USB device not recognized
Unknown USB Device (Device Descriptor Request Failed)

I tried 3 diff USB cords and 2 diff Win 10 computers.

All 3 cords and both PC's see the other Gemma and I completed the whole project.
Neopixel Jewel 10 Minute Necklace

I don't have an Arduino to try to re-flash the boot loader (not sure if that would be the fix)

Is it D.O.A.
