Linux input Binding issue

[Sarayu_Nagarajan]

Hi,
I would like to use an USB Keyboard connected to RPi 4 to implement Linux input binding

But when I add the path, the status is offline.
I tried adding the path in three ways
1./dev/input/event0
2./dev/input/by-id/…
3./dev/input/by-path/…

Someone please do help me solve this issue.
Thanks in advance

I can’t help you with Linux, I know nothing about it.
I don’t know how helpful this sort of thing is?

I’ve also tried these: (before changing permission of ttyACM0): $ cat /dev/ttyACM0 cat: /dev/ttyACM0: Permission denied That demonstrates that user zvika doesn’t have permission to read fro…

If you want openhab to have access to all your input devices you can also make your openhab user part of the “input” group.

gpasswd -a <youruser> input

If you want more fine-grained permissions for the input devices you will have to write a custom udev rule that matches the devices that openhab can access.
