USB Keyboard plugin

I have installed this plugin USB Keyboard, but looks like it doesn't see my keyboard. Am running Octoprint on OrangePi Zero 2 with Debian.
Have tried different keyboards and the Linux itself sees them.
If I click "Device listner configuration" button in the plugin settings I see this:
"Using evdev, additional listener configuration may be needed.
Currently connected devices:

Looks like I have to somehow configure endev listeners, but unfortunately could not find any clear instructions how to do it.

Help would be much appreciated. Thanks :slight_smile:

Did you see Issues · barrettford/Octoprint-Usb_keyboard · GitHub ?
2 entries about empty device list there, one citing the very same message. Both seem to have fixed things by restart or reinstall.

Thanks for the note. Unfortunately steps mentioned there didn't help.
