The current install on 3.7.4 does not have the extensions pack installed (do not mistake this for the VboxGuestAdditions). One can download this pack from Oracle if wanted: https://www.virtualbox.org/wiki/Downloads Be sure to take the sha256 checksums file too as you might need the number later.
To have the same required signature, download their latest for Debian (Buster or Bullseye) here: https://download.virtualbox.org/virtualbox/
Install the downloaded .deb with "dpkg" "aptitude", "debi" or "gdebi" or whatever suits your needs best but not with "api".
After which you'll need to run the following command (in the download directory, or use full PATH) as the inhouse virtualbox GUI option does not work on Elive Linux:
`extension=$(ls -1 Oracle_VM_VirtualBox_Extension_Pack* | sort -g | tail -1 ) ; sudo VBoxManage extpack install --replace "$extension" --accept-license="$( sha256sum "$extension" )"
And, after scrolling and accepting the license, it will be installed and you can connect USB3.0 devices.
To be clear: We don't propagate accepting unread licences blindly .... so use common sense:
