loading required modules 'ucom' and 'uether'

I notice that when booting there are a couple of msgs about
loading required module 'ucom'    .... and 'uether'

Never noticed before as the msgs flash past so quickly. Does this indicate that something is missing from my configuration?
They're probably loaded as dependencies of another module you loaded via loader.conf.
No need. If another module is needed as a dependency it's loaded automatically.
