Problem of HID interface

[alin256]

HID does not seem to work on Raspbian GNU/Linux 11 (bullseye).

I am running the keyboard example from the readme.

Have you followed the instructions from the error?

Yes, I did run the commands from the manual prior to the script.

And I had a shitty Micro-USB cable :(

Thank you for the quick follow-up!
