did you try amidimon in a shell window (amidimon --ports all) or
kmidimon to check if there realy is no MIDI coming in?

Just to clearify: I loose my keyboard which is a notebook keyboard
connected internally via psaux.
In your case, maybe it's a problem of coldplug vs. hotplug. I'd try to
unplug the devices during boot time and plug it in after you logged in.
Furthermore, ensure that in your kernel config, drivers, usb you have
*disabled* usb-midi and usb-audio. Both are OSS and conflict with the
ALSA snd_usb_audio which handles four USB devices perfectly on my
machine (except for the keyboard loss, of course :) .
Best regards
