VirtualBox USB Not Working on Guest Under a Linux Host

Case: VirtualBox 6.1 pass-through not working for Ubuntu guest on a Linux (SolusOS) host. Issue not limited to version or guest OS.


sudo usermod -a -G vboxusers $USER

Note: VirtualBox does not add the current user to the vboxusers groups, seemingly, as a security feature.
