OK, I understand now (I think <grin>).

You are probably using the "ose" version of VirtualBox, which does not include 
USB support.  The ose version is the fully GPL'd open source system.    In 
order to get USB support, you have to download the binary version from   They have Debian packages, which I presume will work in 
Ubuntu.   Their download page shows you how to add the VirtualBox repository 
to your /etc/apt/sources.list file.   Once there, Ubuntu can automatically 
download and install it just like any other package.
