Why?

Whether or not they're built in or modules, they still have to be loaded
for your USB hardware to work.

Whether or not they're built in or modules, you can still disable
individual host control interfaces - the method is just slightly
different (though since the one that works for built-ins ALSO works for
modules, we should arguably be documenting that one instead of the
blacklist trick).

This has solved the bug where ehci was loaded second, therefore the host
controller placed in the wrong mode.
