I had exactly the same problem when updating Gentoo 
recently.  Hans Fugal kindly tried to help me on this list 
on 6 Dec 2005, and sent me this informative link:

http://sourceforge.net/tracker/index.php?func=detail&aid=1353514&group_id=87777&atid=584353

However, that didn't fix it for me.  Now, I have an ugly 
workaround in place:  a little script that gets run 
by /etc/conf.d/local.start, which contains the following:

#! /bin/bash
modprobe snd-usb-audio
cd /usr/share/usb/midisport
fxload -D /proc/bus/usb/004/003 MidiSportLoader.ihx -I \ 
MidiSport2x2.ihx
exit

This works, provided that the MidiSport is always at the 
same USB bus address;  in your case, you will have to 
change the /004/003 to /002/003.

Hope that helps.

I'm interested by your comment "hotplug makes some real 
trouble with USB audio devices".  I'm having trouble 
getting the audio side of my Novation Speedio (a USB audio 
and MIDI interface) to work properly (as per previous posts 
on this list) - could this be related?  If so, what do I do 
to run it without hotplug?

Just one more comment while I'm mailing the list:  if anyone 
uses the Proteus 2000 (a hardware synth), you might be 
interested in having a copy of a spreadsheet I've prepared, 
which has descriptions of all the drums and percussion 
sounds in the ROM it ships with.  Let me know.
