Description

I am constantly having the above error printed on Console. Whilst this is probably not a user facing bug, what could be the reason for this? I am using the latest version on 10.15.2.

I am using Karabiner-Elements with a Unicomp external keyboard.

Feel free to close this issue if it's invalid. Thanks for the great software.

Research direction
Examine the IOKit related code in the Karabiner Elements source, particularly the part that calls IOServiceOpen. Check for any changes in macOS 10.15 that could affect the call. Review the 27 comments for diagnostic information and attempted workarounds. Consider implementing a fallback or error handling if the service open fails.
