I created the file /etc/hotplug/blacklist.d/local with the following

  # uhci_hcd is the host of choice

I don't think a restart of hotplug will do the trick, you'll have to

If you feel a little adventurous you can always use rmmod to remove the
module from a running kernel. I've heard that might cause problems even
though I've never had any, YMMV.

Software is not manufactured, it is something you write and publish.
Keep Europe free from software patents, we do not want censorship
by patent law on written works.

Time is a great teacher, but unfortunately it kills all its pupils.
