With Dan Berrange's changes:

https://www.redhat.com/archives/libvir-list/2013-February/msg00021.html

My 9/11 and 10/11 were no longer necessary.  The 11/11 changes
(qemu_hotplug.c) still apply, but were changed to use the new
virUSBDeviceFree() rather than the previous usbFreeDevice().

Other changes 1/11, 4/11, 6/11, & 7/11 were made as requested.

I rebuilt, retested, and pushed.
