[gentoo-user] problems with usb audio and midi

[luis jure]

i have an internal pci card (m-audio 2496) that works fine on my gentoo
machine, but i'm having problems with usb audio cards and midi devices.
with different devices i get messages similar to this (for the korg
nanokontrol midi controller):

[19616.783860] usb 4-2: new full-speed USB device number 19 using uhci_hcd
[19616.950892] cannot find the slot for index 0 (range 0-5), error: -16
[19616.950894] cannot create card instance 0
[19616.950899] snd-usb-audio: probe of 4-2:1.0 failed with error -5

it works fine on a netbook with xubuntu:

[  671.691137] usb 4-3: new full-speed USB device number 3 using ohci-pci
[  671.859503] usb 4-3: New USB device found, idVendor=0944, idProduct=0117
[  671.859521] usb 4-3: New USB device strings: Mfr=1, Product=2,

[  671.859538] usb 4-3: Manufacturer: KORG INC.
[  672.224152] usbcore: registered new interface driver snd-usb-audio

normally i'm fairly minimalist with my kernels, but now i tried to build
everything that could be relevant, and lsmod shows that i have all the
modules present on the xubuntu netbook, and then some. the first
difference i see is that gentoo uses uhci_hcd, while xubuntu uses
ohci-pci, not that i know what that means...

i would appreciate any help.

It means USB-1.1 as defined by AMD (I think).

lspci | grep OHCI should show if you need it.

Try enabling the last module above and see what you get.

Re: [gentoo-user] problems with usb audio and midi

[luis jure]

thanks for your answer!

actually, i just realized that it's working now. unfortunately i don't
know what of all the things i've been trying made the difference...

$ cat /proc/asound/cards 
 0 [M2496          ]: ICE1712 - M Audio Audiophile 24/96
                      M Audio Audiophile 24/96 at 0xec00, irq 16
 1 [CODEC          ]: USB-Audio - USB Audio CODEC
                      Burr-Brown from TI USB Audio CODEC at

 2 [nanoKONTROL2   ]: USB-Audio - nanoKONTROL2 KORG INC. nanoKONTROL2 at
usb-0000:00:1a.1-1, full speed

the usb audio card is working.

the midi controllers, on the other hand, although recognized by the
system, are not seen by the midi sequencers i tried (rosegarden and
qtractor). i'll have to investigate more, because it's the midi
controllers what i'm interested in.

mmm... lspci | grep OHCI gives nothing, so i guess i'll disable these
modules in the kernel.

thanks again, and if anyone knows how i could actually use those midi
controllers, i would appreciate any help.

Oops!  I gave a bum steer, my apologies!

I meant to have typed:

  lspci -v | grep -i OHCI


As an example, this is what my firewire is using:

# lspci -v | grep -i OHCI
09:00.3 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 PCIe IEEE 1394 Controller 
(rev 01) (prog-if 10 [OHCI])
	Kernel driver in use: firewire_ohci
	Kernel modules: firewire_ohci

HTH.

he, should have noticed that myself... :-)

the output here is very similar to yours, OHCI is used only by the
firewire controller (which i don't use, anyway).

i got the midi controllers working on csound, where i can set the midi
device in the command line. but nothing on the gui applications (qtractor,
rosegarden, musescore...). i have to investigate more...

thanks for your help.

I have no experience with midi devices, but from my understanding you need to 
get jack configured first.

jack is an additional (and optional) layer that provides low latency audio
(and midi) communication between different applications, and between them
and the sound card. if you don't need that, you don't need jack. in no way
is it mandatory.

All I had to do to get my MIDI controller working was to enable "USB 
Audio/MIDI driver" in:

Device Drivers > Sound card support > Advanced Linux Sound Architecture 
 > USB sound devices

It's the only option I enabled there. I have it compiled built-in rather 
than as a module.
