When select() reports a hidraw fd as readable but os.read() returns
empty bytes, that's EOF per POSIX — the device has been removed.

to loop indefinitely on a gone device instead of cleaning up.
Logger enabled checks clutter the code unnecessarily. The checks are
now handled in a custom logger class. Eventually they can be completely
removed in the future.
