I recently ran into a problem when upgrading to Virtualbox 5.0. I was not able to install the Extension Pack, to enable USB 2.0, from the command line. Over at virtualbox.org I found the solution.
On my debian box I used aptitude to install gksu. gksu is a GTK+ frontend for su and sudo (check the man page for more info). Then I executed the following command from the directory where I downloaded the Virtualbox Extension Pack.
After executing this command, my Virtualbox VM would boot up just fine and USB 2.0 controller was active.
