Dear all,

I am trying to get the Teensy 2.0++ running as a USB keyboard for the C64 mini, see https://retrogames.biz/thec64-mini/.

The "Teensy-keyboard" is perfectly recognized by my Linux notebook. But, unfortunately, the C64 mini does not seem to recognize it at all. There is no way to debug this on lower level on the C64. Do you possibly have any idea what the cause of this problem might be? And even more important how to solve the problem?

Thanks a lot in advance for any hint!

Kai
