Hi, I'm using VBox on Ubuntu LTS, I would like to enable the USB support on it, I have already downloaded and installed the VBOX Extension Pack, but when I want to use the option "Add Filter From Device" I can't load my USB key that is plugged to my laptop, so my question is:

1. what do I have to setup in order to have access to my USB devices from my guest OS's?

cheers

Add the user name to the vboxusers group.
See http://www.virtualbox.org/manual/ch03.html#idp55342960

you are right, adding my user to the group vboxusers fix the problem, in fact I have been added but in a wrong way -modifying directly the file group - but using the command usermod all works

best regards

$ sudo usermod -a -G vboxusers username

(replace username with actual user's name)

$ sudo usermod -G vboxusers -a username

P.D: Verify at Ubuntu 16.04.1 LTS with VirtualBox 5.1.8
