from RELENG_5_3

src/sys/modules/usb:
# $FreeBSD: src/sys/modules/usb/Makefile,v 1.15 2004/07/12 21:59:06 imp 
Exp $
[ ... ]

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 
modules.
