Thank you Kim! Did not realize that ugly licensing of the Extension
Pack (except its buggy as hell and allows hijacking the hypervisor
host machine).

But, if the Core VirtualBox is GPL2 then API should be open too and
maybe its time for some Open-Source alternative? :-)

@HPS have you ever considered such operation? If the FreeBSD's USB can
be shared to the userland, maybe that could be also shared to the
Virtual Machine?
