I can’t get any of the Button SHIM examples to work. I get this error:

Traceback (most recent call last):
File “keyboard.py”, line 4, in

IOError: [Errno 121] Remote I/O error

I’ve tried two different Raspberry Pis (a Pi Zero W and a Pi 3 now). I’m planning to use it together with the Unicorn HAT. The Unicorn HAT is working fine. I have also tried removing it but the button SHIM still doesn’t work.

Any pointers appreciated, thank you!
