Hi sigixxx! Impressive work regarding your import/export projects using your "A-keyboard" / "A-Con" approaches! I spent numerous hours trying to replicate what you did with using an Arduino microcontroller as a keyboard and performing automatic keypresses. basically, everything should work, but no matter whether emulating a USB HID device on a standard Arduino or using a dedicated Arduino Leonardo and its AT32u4 uC with its native USB HID capabilities, I can't convince the Switch/Switch 2 to recognize the controller as "just a keyboard". I tried it the default way, deactivated serial via CDC, used the alternative bootkeyboard approach, modified the HID.c/.h files - but nothing, the Switch just won't recognize the key strokes.
So any guidance or hint on how to proceed would be greatly appreciated!
