Unknown USB Device

Unknown USB Device
« on: November 27, 2015, 12:56:00 PM »
Everything was working fine and then it wasn't.  I can no longer connect to my TinyDuino.  The Device Manager says "Unknown USB Device ( Device Descriptor Request Failed)".
I have tried:
    Reloading the FTDrivers.
    Changing USB Cables.
    Connecting with and without the TinyDuino attached to the USB adapter
    Searching the TinyCircuits forums and reading lots of other places.

Could I have damaged the USB adapter some how?

Thanks for your time.
