from RELENG_5_3
src/sys/modules/usb:
# $FreeBSD: src/sys/modules/usb/Makefile,v 1.15 2004/07/12 21:59:06 imp

SRCS+= uhci_pci.c uhci.c uhcireg.h uhcivar.h
SRCS+= ohci_pci.c ohci.c ohcireg.h ohcivar.h
SRCS+= ehci_pci.c ehci.c ehcireg.h ehcivar.h
SRCS+= opt_bus.h pci_if.h
.include <bsd.kmod.mk>
so the usb module is ready for ehci.
In fact, I use to take-off any udb support form kernel and go only with
