dmesg log flooding about co2meter

[vfilimonov]

Hello @satter

Thank you for the report. To be honest I don't know why does it happen, since this logging is not set up explicitly by co2meter (neither do I fully understand what and how logs to dmesg).

Do you have any idea how to suppress it?

These logs seems to be generated by hid-core driver: https://github.com/torvalds/linux/blob/master/drivers/hid/hid-core.c#L2020
Similar log line appears on hid device connect:

Maybe it is related to the way co2meter reads data from device? For example, co2mond does not trigger such logs for the same device
