From an mail I send earlier:

        [snip]
        
        [spinymouse@email-addr-hidden ~]$ lsmod | grep snd_seq_midi
        [spinymouse@email-addr-hidden ~]$ lsmod | grep snd
        [snip]
        usbcore 147434 5
        snd_usb_audio,ohci_hcd,snd_usbmidi_lib,ehci_hcd,usbhid
        
        [snip]
        
And now:

        [spinymouse@email-addr-hidden ~]$ lsmod | grep snd_seq_midi
        snd_seq_midi 5328 0
        snd_seq_midi_event 5692 1 snd_seq_midi
        snd_seq 50881 6
        snd_seq_midi_event,snd_seq_dummy,snd_seq_midi
        snd_rawmidi 18479 4
        snd_hdspm,snd_usbmidi_lib,snd_mpu401_uart,snd_seq_midi
        snd_seq_device 5300 4
        snd_seq,snd_rawmidi,snd_seq_dummy,snd_seq_midi

Perhaps it was loaded, when I opened Muse2, however, on my system
everything is ok and after I plug in an USB MIDI interface and a KORG
nanoKONTROL snd_seq_midi wasn't shown, but usbcore was shown.

usbcore is missing for the output the OP posted.

Ralf
