Installing the VirtualBox Extension Pack
This is needed for USB 3 and is a requirement for running the VM, even if you are not actually going to use USB 3.
Assuming your host is running Ubuntu,
sudo apt install virtualbox-ext-pack
Or available via https://www.virtualbox.org/wiki/Downloads. If downloading manually, make sure the extension pack version number matches the VirtualBox version number. Distributions do not always use the latest version. Installation is under File/Preferences/Extensions.
