So :
* module snd_usb_audio is already loaded
* after running aj2midid -e, keyboard is still missing from ALSA and JACK
tabs...
It's true that I was surprised that the keyboard did not appear in
/proc/asound/cards but as it does appear in amidi -l, i'm thinking that
alsa is correctly recognizing the keyboard... Could i be wrong?
Thing is I'm not sure if this is an ALSA issue or jack/qjackctl one.
how could i troubleshoot this ?

Ok. It does need to be listed as a card in /proc/asound/cards, just as a
webcam with built in mike (although not a soundcard as such) will have a card
entry and uses snd_usb_audio. So why isn't it there?
Does it need firmware loading? I know some M-audio keyboards do. My Evolution
keyboard doesn't, but someone with the same as yours will say.
Have you tried it in a different USB slot if you have spare ones? Not in a
hub as some USB things don't like hubs.
The only other thing I can think of is that both the sound card and the
keyboard are trying to grab card0 and the soundcard is winning, thus the
keyboard can't use it. Now I've seen this the other way round due to the USB
coming up early in the boot process and my keyboard grabbing card0 leaving no
place for the actual soundcard.
This is a very old problem, but may for some reason be happening in your case,
so I suggest putting some index options in /etc/modprobe.d/options, which
will at least confirm if that is the problem or not. See below.
options snd_hda_intel index=0
options snd_usb-audio index=1
Best to reboot and then see if /proc/asound/cards lists both.
If not I'm a bit perplexed.

I must say that I didn't take much notice of that at the time, but was more
taken by the missing card in /proc/asound/cards.
I see his lsusb also lists an integrated webcam no doubt with a mike which
will be using snd_usb_audio, which if that is so, that's not showing in the
cards list. I know I'm clutching at straws but wonder if the webcams mike is
also trying for card1 and causing some sort of conflict with snd_usb_audio.
I suppose it's worth unplugging the keyboard and seeing if snd_usb_audio turns
up in /proc/asound/cards for the webcam mike as card1.
If it does I'm not sure how you set the index options for multiple devices
using snd_usb_audio.

the
snd_usb_audio module isn't loaded, or you've forgotten to switch the
keyboard
on. Have a look in lsmod to see if the module is showing there.
If not, load it with.
sudo modprobe snd_usb_audio
Then see if the keyboard shows up in the cards list.

Lets have a go at the USB problem. Your lsusb shows a webcam. I can't find any
details about it on the web, but presume there's a mike on the card which
will need to use snd_usb_audio. I'm guessing there may be a conflict where
both usb audio devices are trying to use snd_usb_audio in the same card slot.
So first thing to try is to remove the midi keyboard from the machine, then
see if anything turns up in /proc/asound/cards, like hopefully the webcam
mike using snd_usb_audio as card1.
If by some miracle it does, you need to add an options line
in /etc/modprobe,d/options to cover both devices, the webcam mike and the
midi keyboard.
Run lsusb -n and you should see the Vid/Pid's for both devices in hex. Add
the following options line, removing the snd_usb_audio options line I gave
you yesterday but leaving the one for the soundcard.
[courtesy of a post on Linux Musicians forum]
Look at the output of “lsusb” and “lsusb -n” for the vendor/product IDs of the
devices, then specify these IDs in the vid and/or pid options, in
hexadecimal. For exampe, if your first USB device has IDs 0123:4567 and the
second 89ab:cdef, use the line
options snd-usb-audio index=2,3 pid=0x4567,0xcdef
You will need to change the 4567 and cdef for whatever the pid's are for the
webcam and midi keyboard.
Right. Go for it! He says, not holding out much hope.

ok so here are the result for the various logs but unfortunately, we're not
learning much here. the webcam does not show up when the keyboard is
plugged in or unplugged....
i might have another lead though. I looked into the system logs when
plugging/unplugging the device and here is what showed up
[ 782.208027] usb 7-1: new full-speed USB device number 8 using uhci_hcd
i was more or less expecting usb_snd_audio to be loaded. Any ideas ?

Yup but it still doesn't show up in qjackctl, which is really really
strange.
I really don't get why it doesn't since it's properly recognized by ALSA.
Does anyone know from where qjackctl gets its MIDI device list ?

I'm tweaking around qjackctl's parameters right now.
I noticed that there is no MIDI driver (bottom left of setup panel)
selected in my setup. Is that usual or should I set it to another value
than none ?
cheers

the MIDI driver selector only exists to start up a "builtin bridge" between
teh world of ALSA MIDI and JACK MIDI. neither of its options are good. you
should use, as mentioned way up-thread:
a2jmidid -e
and yes, some developer should fix this pathetic state of affairs.

You'll still need to use a2jmidid -e to get Jack to see it.

Yes. Jack depends on ALSA drivers to work with hardware MIDI devices, just
like it depends on ALSA drivers to work with hardware audio devices, except
for FireWire devices where jack depends on ffado/freebob. Jack does not have
its own hardware drivers.
Would a message found in dmesg like :

Yes, it is a good sign. Answering your previous question:
Does anyone know from where qjackctl gets its MIDI
device list ?
The ALSA tab is filled from the ALSA Sequencer list of ports, which can be
hardware devices or software applications.
The MIDI tab list comes from one of those bridges that provide MIDI support
to jack.
If you should solve the problem at the ALSA level, I guess that you will be
able to solve the problem with jack as well at the same time.
ALSA provides a number of kernel modules. You can list them with this
command:
$ lsmod | grep ^snd
My guess is that some modules are not automatically loaded in your system.
Summing up your previous diagnostics, the ALSA hardware driver (snd-usb-
audio) recognizes your device properly:
$ cat /proc/asound/cards
1 [v2 ]: USB-Audio - USB Oxygen 8 v2
M-Audio USB Oxygen 8 v2 at usb-0000:00:1d.1-1, full
And the ALSA raw MIDI interface (snd-rawmidi) is working properly as well:
$ amidi -l
Dir Device Name
IO hw:1,0,0 USB Oxygen 8 v2 MIDI 1
In your previous messages it is not clear if the ALSA Sequencer interface is
working or not for you. To verify, there are several tests that you can try.
$ cat /proc/asound/seq/drivers
snd-seq-midi,loaded,2
$ cat /proc/asound/seq/clients
Client info
cur clients : 4
peak clients : 5
max clients : 192
Client 0 : "System" [Kernel]
Port 0 : "Timer" (Rwe-)
Port 1 : "Announce" (R-e-)
Client 14 : "Midi Through" [Kernel]
Port 0 : "Midi Through Port-0" (RWe-)
Another way is the ALSA sequencer player (from the ALSA tools collection):
$ aplaymidi -l
Port Client name Port name
14:0 Midi Through Midi Through Port-0
20:0 MidiSport 2x2 MidiSport 2x2 MIDI 1
[...]
Or the ALSA Sequencer event monitor/receiver:
$ aseqdump -l
If some or all the above tests failed, my guess is that the ALSA Sequencer
modules aren't loaded. In that case, you may try this command:
$ sudo modprobe snd-seq-midi

Ok Pedro thanks a lot for the insight !
Very interesting to know how things work from the inside :)
I'll try the various commands tonight and give a report here as soon as
it's done
Thanks again and cheers
