Plugging in an old USB stick cause the warnings in the last 2 lines below in
dmesg and /var/log/messages :

ugen3.3: <LEXR PLUG DRIVE> at usbus3

error=63)

This is harmless for my usage (mounting the content explicitly works). I don't
know if it would impair automounting it.

My understanding is that spaces are not valid serial number characters and
somehow left-padding it like that was wrong from the device manufacturer, but
the way FreeBSD quotes them doesn't seem entirely successful.
