In fact, the FreeBSD ports tree Makefile for QEMU does basically the
same thing -- search for 'HOST_USB' in
http://svnweb.freebsd.org/ports/head/emulators/qemu-devel/Makefile?revision=319450&view=co

On FreeBSD-current libusb has grown the functionality required by
QEMU's recent libusb USB host code, and I'm using that.  I assume that
the current BSD host USB code works on NetBSD and OpenBSD, but don't
really know; possibly they can switch to libusb as well.
