vboxusers issue sorted

A relatively simple thing to fix it seems, unless you don’t know about it! I had the issue that my VirtualBox install on Mint wasn’t allowing access to the USB ports etc and the fix seemed to be to add my user to the vboxusers group. Sounds simple enough, and if you follow the instructions here (http://forums.linuxmint.com/viewtopic.php?f=90&t=91855) it is. 🙂
