USB Passthru – Attaching a physical USB to VirtualBox client doesn’t work out-of-the-box. Apparently the solution is very very simple but not trivial. After messing around with kernel modules, VB settings, forums, docs; I found the solution deep in one of the forums:
When VirtualBox is installed, it adds a group named “vbxusers” to /etc/group.
In order USB Passthru to work, the user who is running VB on the Linux host, (“cayfer” in my case) must be added to this group; logout and login; vola…
Relevant /etc/group entry should look like:
vboxusers:x:130:cayfer
