kldload/kldunload have nothing to do with it. If the drivers are
stupid, that's their own damn fault. usb is a known problem child
that needs to be fixed. If there are others that need to be fixed,
then fix them. You have the source, use it :-).
I've used kldload/kldunload extensively in the development of cardbus,
pccard and pccbb. I'd be totally lost w/o it.
