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.
