   after:

 rmmod usb-midi
 modprobe snd-usb-midi

 lsmod reports:

Looks good. I also have usbcore loaded (using snd-usb-audio), not sure if that
is relevant. Maybe try loading usbcore before you plug in the midisport?

...
  and the log reports the same when plugging in the
2x2:

 Mar 22 19:14:08 umatic1 hub.c: new USB device 00:1d.0-1, assigned address 36
 Mar 22 19:14:08 umatic1 usb.c: USB device 36 (vend/prod 0x763/0x1001) is
 not claimed by any active driver.
 Mar 22 19:14:11 umatic1 /etc/hotplug/usb/ezusbmidi: load
 /usr/share/usb/ezusbmidi/ezusbmidi2x2.ihx for 763/1001/1 to 
OK, nearly there! I think your midisport 2x2 is missing from modules.usbmap.
Go to /lib/modules/`uname -r`/
and grep 763 modules.usbmap. You'll probably won't have a line for 0x1001
(in the 4th column). You can add it here. Best copy one of the other lines, like
snd-usb-audio        0x0083      0x0763   0x1002    0x0000       0x0000       0x00        
0x00            0x00            0xff            0x00               0x00               0x0
Take care with the tabs! (I moused this one in).

I'm on a 2.6 kernel here, but I don't think this was different in 2.4.

FYI, myself I use some slightly different tools from http://usb-midi-fw.sf.net.
Look like you can also create /etc/hotplug/usb/midisport_fw.usermap with:
midisport_fw 0x0003 0x0763 0x1001 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0
in it (no tabs here).

If that all doesn't do it, it must be related to usbcore. My modules.dep has:
/lib/modules/2.6.3-mph1/kernel/sound/usb/snd-usb-audio.ko:
/lib/modules/2.6.3-mph1/kernel/drivers/usb/core/usbcore.ko
/lib/modules/2.6.3-mph1/kernel/sound/core/snd-rawmidi.ko
/lib/modules/2.6.3-mph1/kernel/sound/core/seq/snd-seq-device.ko
/lib/modules/2.6.3-mph1/kernel/sound/core/snd-pcm.ko
/lib/modules/2.6.3-mph1/kernel/sound/core/snd-page-alloc.ko
/lib/modules/2.6.3-mph1/kernel/sound/core/snd-timer.ko
But that could very well be different in 2.4.
