Should this be a Warn? It's very unusual, that's for sure...
However, I believe it should be Debug. Any node that doesn't have USB devices attached will be flooded with logs stating that no USB devices. In many clusters, nodes don't have a USB device attached and this information is only useful if debugging in those cases.
There was an original comment that stated:
