So I uploaded a sketch to my Leo but now my computer wont recognize it. It does not show up at all. Also when I press the reset button, the Leo just sits there. Before it would blink slowly. So I need a way to erase the sketch or reset the Leo some way.
All help is appreciated! 
Btw I ran the same code on my uno and it worked fine. The code was designed to turn a Gamecube controller into a USB controller. I don't know if this helps at all with solving the problem...
Tried using an uno to burn the bootloader but I keep getting an error. Don't have access to arduino and stuff now but I will try to pur the error code up here.
