USB Midi Keyboard Not Detected

[phobos13013]

I have just picked up a brand new Akai for midi controller as I wanted experiment with some stuff like fluidsynth and rosegarden etc etc.

When I plug it in lsusb does not recognize it fully... it is given an address but no specs come up for it. I have midi gadget support active in my kernel and all the software necessary. Anyone have any pointers to get gentoo to recognize the device? Is there a preferred hardware list or anything like this? Any info is appreciated

edit: btw not getting anything on aconnect -i either... just kernel connections only

Regards
Christoph

Would it be an Akai MPK49?
what is the output of lsusb?
whats the output of lsmod?

Its an Akai Mini actually here is the specific output... not very informative sadly:

[MarioCorleone]

Is this controller brand new or used?
are there settings for "output" on the controller?

when i plugin my MPK49 to my laptop not setup for a DAW here is what lsusb shows

[phobos13013]

Nothing just:

How did you build kernel, all included nomodules?

yuup... everything is built-in. Do I need to make the midi parts modules is there a reason if so?

never seen someone build a kernel with everything built in. tends to make a HUGE kernel. IMO, i would build my devices as modules.

Whats the output of "lspci -k"

And..

[phobos13013]

lspci -k

Bus 005 Device 002: ID 2011:0715

It mean, device is attach to usb port 005 (that is Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub ) and device manufacturer is 2011, and device type is 0715

Alas for you, from mario18 you can see you should had got a 09e8 manufacturer value (well, with a diff device type value as they aren't the same device).
Next to that, it match pair manufacturer:device to attach a string to it, this is not really a problem just that nobody has report what 2011:0715 kind of device is yet.
That's not really "that bad", as some manufacturer use other manufacturer device and their code is not their one, but the other manufacturer code. But it's also not really "that good" too, specially has nobody knows who is "2011" manufacturer. The bad part is really having a buggy code there might show the device report stupid thing and is not working as it should.

What you should look at:
- Is there a device option to enable some usb type
- Try attach the device to your Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub like mario18 using it on an usb 2 port.
- Check the usb cable for trouble (hole/pinch/badly plug)...
- If the device is not well feed (by energy, it might appears but gave random result, kinda like you get), that's something putting it in usb2 port may fix.
- Might also be a trouble with usb drivers (ohci in use right now), that's again something putting it on usb2 port may fix (usb2 use ehci)

So for me, you really should plug it to usb2 port (you could also pray while doing it).

If it doesn't work, try it on another kernel (for kernel issue), any livecd ; if it still, try another computer (i know it's not "that easy" to get your hands on one, but neightbors could help).
If the three fail, you really should think about considering the device is in trouble (that's more common than what people think, generally once it works, it really works for years, and trouble appears more when the device is brand new and components not yet used).

What does dmesg say when you plugin the controller?

[phobos13013]

OK.. sorry for the delay in response I am uber sick right now and on some meds also on the west coast so it was late for me and I passed out big time.... anyway im back and I think you are right about the usb thing... but i dont know how to fix it... Every plug i put it in it seems to put it on a 1.1 usb bus. Now this is veeeery old computer as can be seen from specs but I have three separate usb locations three on a bus in the back two on a bus in the front and like four on a bus on add-on card i have that also has firewire ports etc (extension bus essentially). Obviously at least one of those is recognized usb 2.0 but nothing plugsin as such it appears....

meanwhile here is the pertinent part of dmesg when it runs and looks the same on any bus:

dmesg | tail:

[MarioCorleone]

post output of

[phobos13013]

dmesg | grep usb

[MarioCorleone]

OK, we're really close...

This is where its going wrong

[phobos13013]

mario you are a trooper hanging in with me this long...hope we can find this fix

here is my USB kernel config:

Here is my SND kernel config:

https://bpaste.net/show/28517bd5c7fa

let me know where to go from here

Ok... so currently on 3.18.12 but i noticed that 4.0.5 has been installed during a recent world update while getting this stuff working but i sort of glazed over that... I am currently installing the kernel parts on my 3.18.12 release but I'd like to move up to 4 unless there its unknown or known bad to move up to 4 yet. If it doesnt matter I will still probably wait until i get all this working for confirmation. Will report back shortly with the kernel upgrades...

I do not see the F_MIDI and F_HID in my kernel tho... is there a way to activate those so they can be seen....?

OK... no change to device with doing what I could... but it wasnt perfect.

a) I was able to get the EHCI components and HDA_PATCH_LOADER built-in
b) The USB_AUDIO and G_HID had to be built as modules since it appears I can only select one Gadget "tree" to be built-in at a time
c) THE F_MIDI and _HID are not found in my kernel... is this something new... something old?

Regardless... with the above changes (or not changed) lsusb still gives the same output... also lsmod is blank still so do I need to tell those mods to load or anything?
