keycode 52 = y Y y Y bar U203A guillemotrightBut under wayland i had to change to evremap (https://github.com/wez/evremap)
keycode 59 = comma semicolon comma semicolon less multiply periodcentered
keycode 60 = period colon period colon greater division U2026
To automatically activate remapping by a systemd service i did following

I got multiple USB devices working with em28xx module.
Usually a module option gives the em28xx module the order of the devices if not automatically detected
(ex. options em28xx card=80,92,9,9).
But the order at boot is every time different (order for module option not usb detection).
The only working solution for me is to manual loading, scan the order from kernel logs, unload and load with the scanned order:
/etc/modprobe.d/em28xx
blacklist em28xx
blacklist em28xx_v4l
blacklist em28xx_dvb
blacklist em28xx_rc
