Re: [LAU] programs (eg. rosegarden) don't see my usb midi device

update:
I booted into an ubuntu live cd and the um-1s worked, I took a look at the loaded modules (a LOT!):
(the arrows shows which modules I did not have)

snd_rtctimer
snd_usb_audio
snd_usb_lin
--->snd_hwdep

^these were loaded after inserting the device I think

snd_hda_intel
snd_hda_codec
--->snd_pcm_oss
--->snd_mixer_oss
--->snd_pcm
snd_seq_dummy
snd_seq_oss
--->snd_seq_midi
--->snd_rawmidi
snd_seq_midi_event
snd_seq
--->snd_timer
snd_seq_device
--->snd

--->soundcore
--->sndp_age_alloc (used by snd_hda_intel, snd_pcm)
--->usbcore(used by snd_usb_audio a snd_usb_lib)

should I load some of these modules?
or recompile the kernel with more things as module?

PS: i tried to load for ex. snd-hwdep,snd,snd-rawmidi,snd-page-alloc,soundcore but they don't exist

Thank you all,

ale

I'd like to understand what's the problem...
Maybe everything would work after a complete reinstall...

Waiting for other hints...

I answer late, anyway this is the output of aseqdump -l:

 Port Client name Port name
  0:0 System Timer
  0:1 System Announce
 14:0 Midi Through Midi Through Port-0

It doesn't appear :(

Does it appear in the output of "aseqdump -l"?

Thanks for the help.
Actually snd-seq-midi wasn't loaded.
Anyway even after loading it with modprobe I did not see changes (tried to load before and after inserting the um-1s)

This is my lsmod: (without snd-seq-midi)

PS: I recently upgraded udev to version 108 (using gentoo) can this be linked to my problem (it didn't work before, but maybe with that module...)?

Bye,thanks

Some old kernels do not automatically load the snd-seq-midi module;
make sure that it is loaded.
