Are you actually getting a "Unknown USB Device" error when you plug it in?

yes.
plus nothing happens when i hit the reset button. red led will not come on, and device manager wont even see it when i hit the reset. the pro trinket will reset the device manager but not the gemma.

Have you downloaded and installed the drivers and the Adafruit IDE for Gemma? https://learn.adafruit.com/introducing- ... troduction
