Description eNca 2018-10-11 16:27:45 UTC 
When I connect my USB keyboard "Microsoft Natural® Ergonomic Keyboard 4000" to the USB port then these error messages appears in the /var/log/messages:

> Oct 11 17:24:41 vvotipka-gentoo kernel: <27>[ 1264.059078] udevd[7879]: Error calling EVIOCSKEYCODE on device node '/dev/input/event7' (scan code 0xc022d, key code 103): Invalid argument
> Oct 11 17:24:41 vvotipka-gentoo kernel: <27>[ 1264.059085] udevd[7879]: Error calling EVIOCSKEYCODE on device node '/dev/input/event7' (scan code 0xc022e, key code 108): Invalid argument

I have found the solution (https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1389201/comments/6). When I remove these lines from /lib/udev/hwdb.d/60-keyboard.hwdb and run udevadm hwdb -u then the problem disappears:

My environment: 
Gentoo Linux on MacBook Pro
sys-apps/hwids-20171003
sys-fs/eudev-3.2.5

Very similar problem appears for Logitech Pefromance MX wireless mouse. When I connect the receiver to the USB port then these errors appears in the /var/log/messages:

In this case I need to remove this part from the same file:
