How to set up USB for Virtualbox? USB in different versions of Virtual Box

For use of the USB in Virtual Box 3.x need a puel-version. From Virtual Box > 4.x USB 1.0 are supported in the OSE version installed from Software Center. For USB 2.0 or USB 3.0 (from Virtual Box > 5.x), we need to install a extension pack free for Downloa D from Oracle. This would make our virtual box a puel-version (see this question in details on what to install Virtual box from the Oracle Repository).
