It cant because only the non-open source version supports USB, but I installed this version by muself which wasnt much of a problem.
Thank you, now it works for me too. But how do I perform: "/etc/init.d/vboxdrv start" at boot time?
Since I got this message.
As our installer does not recognize your Linux distribution, we were unable to
set up the initialization script vboxnet correctly. The script has been copied
copied to the /etc/init.d directory. You should set up your system to start
it at system start, or start it manually before using VirtualBox.
If you would like to help us add support for your distribution, please open a
new ticket on http://www.virtualbox.org/wiki/Bugtracker
VirtualBox has been installed successfully.
Edit: I've posted a ticket for Pardus support at virtual box.
