recently i got my Digispark with USB.
I tried many things to use it like an rubber ducky. But it seems not quite so easy to use the Digi because many Keys were not send right.
I created a small list for the german Keyboard where you can look to get the right Symbols or ö ä ü.
I hope that someone find it useful took me a heck of time
ALSO: The list is not yet complete im still working on this.
