That's possible, but I can't find the way to do it right now.

You may find it easier to set up usbd.conf(5) to automatically mount
the device when it's detected.  Or, alternatively, to make a symbolic
link from a constant name in /dev (which is pretty close to what you
asked for originally).

Be well.
