sorry i'm currently on holiday but i'll be back Saturday and ill have a go
I've had the same issue running on Pop!_OS 22.04 LTS.
Can you try if specificying devices explicitly via defcfg works?
This and running kanata under sudo privileges worked for me. Thanks.
I'm also having this issue, I believe. Is there a way to solve it without giving kanata root privileges? I'm trying to use the uinput setup as described in kanata/docs/setup-linux.md, but that doesn't appear to support directly specifying the device. Or at least, directly specifying the device gives permission errors, and not specifying it leads to kanata saying that it can't find any devices.

I would be interested in that as well. It's just as you described for me: directly specifying the device I only managed to solve with sudo privileges and not specifying it as described in kanata/docs/setup-linux.md did not work ("No keyboard devices were found").
Is the user you are executing kanata as part of the input group? Or otherwise has permission to read the relevant input device file?
okay update: user was part of both input and uinput groups, and after rebooting, directly specifying linux-dev /dev/input/by-id/... in defcfg in the config file worked. not sure why a reboot was necessary, but glad it works, at least. sorry for the trouble!

Can you show your config file?
