Hello devels,
just a "short" question.
I own a piece of hardware called Noah EX. It's a "tactive instrument
modeller". Wich means, that it calculates the behaviour and sound of
instruments with help of loadable software plugins.
This is well done by the device so far.Because that works without any
help from a computer.
My question is based on the matter, that this device owns an
usb-interface, that is capable of transmitting audio and midi data.
It supports:
Sampling Rate 44,1khz (this is the only one)
Internal audio data width 32 Bit; (might be 16 external)
USB Audio In: 2 channels
USB Audio Out: 6 channels
USB Midi In
USB Midi Out
ADAT Out: 8 channels
Wordclock In
My goal is to get this device working with the alsa usb driver, because
the output of lsusb -v leads me to the hope, that it has a standard usb
audio interface.
My configuration:
Mainboard: Asus A7N8X
Kernel: 2.6.2 Vanilla (vanilla means unpatched from kernel.org? that's
right, isn't it?)
I only applied the changes in capability.h to "satisfy" the jack-audio-
connection-kit.
Just plugging it to an usb port on my linux box results in an output in
/var/log/messages, that reads:
Feb 5 00:28:33 chief kernel: hub 1-2:1.0: port 4, status 101, change 1,

Feb 5 00:28:33 chief usb.agent[7038]: ... no modules for USB product
1107/102/100
What I discoverd yet, is that the device is offering two configurations.
And the second is the audio and midi related one. The first seems to be
the configuration "channel".
snd-usb-audio is enabled (and working), because of having an M-Audio
Midisport 4x4 as an additional Midi-In and Out device to my other
soundcards, using the drivers emu10k1, intel8x0, ice1712 and virmidi.
(With the fact, that Midi-In on the Midisport is only working with USB
2.0 disabled in the BIOS, but this may be a bug in the ehci part of the
kernel. Not talking about unplugging the Midisport blocks the usb part
of the kernel; even with only USB 1.1 enabled in the BIOS.)
I was gathering around for some information about the usb-audio driver,
but couldn't get the information, I was looking for.
Is it always a requirement, that an usb audio(midi) device has an entry
in usbquirks.h or is that only for special(non standard usb audio
compling devices)?
For the reason, that it requires an entry in usbquirks.h, I attached the
output of lsusb -v. Maybe it might help.
I'm also willing to do some testing with any hints.
