Diff to v2[1] version:

I did some basic testing today, and I'm seeing the device appear and disappear
in the guest, which is great and much nicer than my ugly udev rule hack. I did
find what I think is a bug though: if the USB device is plugged in at domain
start, unplugging it while the domain is running does not cause it to
disappear, and subsqeuently replugging it into the host causes a second
instance of the device to appear in the guest.
Can be applied on:
