Comment # 11 on bug 1208941 from Larry Finger

I found a bug in our wrapper around the VirtualBox GUI. It will be added to our
next push of the package. In the meantime, edit (as root) /usr/bin/VirtualBox
and change the "echo" line in the else branch to add the $INODE part.

devrules()
{
    /usr/lib/virtualbox/VBoxUSB_DevRules
    if [ $? -eq 0 ] ; then
        # User accepts the risk
        touch ~/.config/VirtualBox/enable
        rm -f ~/.config/VirtualBox/disable
    else
        # User declines the risk - save the inode
        echo "$INODE" > ~/.config/VirtualBox/disable
        rm -f ~/.config/VirtualBox/enable
    fi
}

I will also upload the corrected file, which you can download and copy to 
/usr/bin/VirtualBox.
