[USB Rubber Ducky DFU mode]

When I attempt to flash the duck without SD card, there is no LED.

 

And I was able to execute the Hello World payload twice with the replay button, so my button isnt broken.

 

Any other ideas?

[USB Rubber Ducky DFU mode]

I have attempted to put my Rubber Ducky into DFU mode and I have been unsuccessful. I have plugged the USB into my computer (Windows 10) while holding down the small black button. I have tried this with and without the SD card inserted into the duck.

Please Help
