jDevSD

It lights up red regardless when the SD card is removed.

Ok so let me preface this with an apology in case my google fu has failed me. I've had a ducky for about a week now and have to be able to flash new firmware to it. I know you have to push the button during insertion to enter dfu mode. I have tried on a mac, windows 10 VM, and a kali box and have to get it. Nothing even seems to see it... Is there a way to verify dfu mode? Im hoping its not a faulty pin. Any help is greatly appreciated!!
