Every few months I’m setting up a new virtualbox OS. I always forget that on a Linux host you need to add your username to the ‘vboxusers’ group (and need the extension pack). Usually in my case, its a linux host, with windows guest…
- Install virtualbox extension pack to support USB devices, enable USB 2.0/3.0 support in machine settings.
- ‘sudo usermod -aG vboxusers <someuser>’ then logout/login to put this into effect.
USB devices should now show up for OS guests.
