virtualbox: are there two versions?

[Leander Jedamus]

Hi!

I recently read in a magazine that virtualbox from oracle comes in two 
different flaviours: an open source edition (which is in the 
repositories) and a proprietary one, which has usb-support, what I need. 
Do I have to install that package without apt-get? I like that 
update-thing from ubuntu, but did not find the proprietary package in 
the repositories.

Thanks in advance
