I believe this is planned to be the furture for the usb stack. Currently
it appears to be in perforce
http://perforce.freebsd.org/branchView.cgi?BRANCH=usb

no idea if theres a patch set or tarball for the general public, but its
being activley worked on. the freebsd-usb list might be a better place
to ask.
