I'm running FreeBSD 8.2-STABLE (host) and VirtualBox 4.2.0. I have followed the steps in http://wiki.freebsd.org/VirtualBox to make USB devices available to VirtualBox guests, and that works (e.g., a Win2K guest can use a USB scanner I have attached to the host's USB interface). I'm planning another guest running FreeBSD (probably 9.X) and I'd like to have a USB wifi dongle (probably a run(4) device) that is visible to the guest as a network interface, but that is not visible to the host. I think this can be accomplished by preventing the run(4) driver on the host from seizing the usb device, and then configuring VirtualBox to let that USB device be visible to the guest. I think I can prevent the host's usb driver from loading by editing (or overriding?) the matching entry in /etc/devd/usb.conf which would prevent the run(4) module from loading, but that's kind of a big hammer. Has anyone else solved a similar problem? Is there a finer-grained approach? thanks, ~!paul -- G. Paul Ziemba FreeBSD unix: 1:21PM up 22 days, 18:59, 19 users, load averages: 0.41, 0.37, 0.30
