Yes, from your logs it appears that hotplug is not doing anything
(loading the firmware and so on).

I think the file that matters for hotplugging is:

That one has the id numbers for the supported interfaces. Check that it
is there (it is part of the ezusbmidi rpm). For that file to have effect
you have to install the latest hotplug rpm available in the site
(version 2002_08_26-1). Older versions have to have those ids in the
global hotplug configuration file. I'd first check that you have that
file and the latest hotplug.
