Solid red light on Gadget 2

I bought a gadget 2 yesterday and when I first plugged it into my laptop, it had a green light on it. As I was updating it on EOS, the update failed and it now won't get recognised at all by my PC. I've tried everything I could find to get it to work and it still won't do anything. The only other thing I can think of is reinstalling windows but I don't want to do that. Does anyone have any ideas on how to fix this?
