Yeah, just added the delay and it made no difference. I had two windows error sounds and randomly chrome opened on my machine? But random things happen every time I plug the duck in. Did I need to do a initial flash or anything as I believed it was all setup. And all I have done was created my inject.bin with the ducky decode on Darens Git hub and plonk it on the root of the sd card? Any advice would be great! Thanks ;)
