Defer boot-time exploration of USB busses until all devices in the
system have been attached, but no later. This ensures that we do
not explore ohci or uhci busses before the companion ehci controller
has been initialised, so it should fix the problem of multi-speed
USB devices getting attached as USB 1 devices first and then
re-attached as USB 2.
This fixes issue #946 for qemu and my HP Compaq 6710b laptop.
Obtained-from: FreeBSD/usb.c 1.104 to 1.106 and NetBSD/usb.c 1.35
