[alsa-devel] trying to get an eleven rack to work
Hi.
I bought and would like to get an eleven rack interface to work. It is a usb gutiar amp emulator/audio interface. It is a avid/digi device that normal uses asio vendor specific drivers.
When I plug it under Linux I get the following:
ls -l /proc/asound/card1 total 0 -r--r--r-- 1 root root 0 2012-03-17 18:57 id -r--r--r-- 1 root root 0 2012-03-17 18:57 midi0 -r--r--r-- 1 root root 0 2012-03-17 18:57 usbbus -r--r--r-- 1 root root 0 2012-03-17 18:57 usbid
lsusb -v for the device returns:

I am completely new to this, but if someone can point me in the right direction...I would appreciate it, I have just started trying to learn about this and my limited understanding is that it would require some additional coding in the quirks code for the snd-usb-audio driver. How can I determine what the quirks are? Does there exist any documentation or how-tos that I can look for on this? Any help or suggestions are appreciated.
sincerely, David Alexander

Appologies to all for 2 copies I forgot alsa-devel.
David,
So it should show up when plugged in as a midi device but the audio i/o is typical m-audio almost but not quiet compliant.
so you do need a quirk based on reading the lsusb output above my guess is:
Interface 0 is a DFU firmware upgrade Interface 1 is really custom (perhaps some sort of custom control/management thing tho I would of thought they'd use midi sysex for that) Interface 2 is the midi Interface 3 looks like maybe a usb mixer without a descriptor? but that's a guess. Interface 4 is potentially usb2 audio output Interface 5 is potentially usb2 audio input.
So if you were to look at the fast track ultra quirk building something that can get audio in and out should be straightforward. (ignore the mixer using QUIRK_IGNORE_INTERFACE or whatever the right macro name is)
that said. there is a devil in the detail here... which is..
Transfer Type Isochronous Synch Type Asynchronous Usage Type Implicit feedback Data
on interface 5 indicates this is implicit feedback used for clocking control... of the output on interface 4 This is not supported by the alsa snd-usb driver but work is underway to add support for this usb transfer mode.

Grant.

Interface Association: bFunctionClass 255 Vendor Specific Class
Indeed.
bInterfaceNumber 1 bInterfaceClass 255 Vendor Specific Class bInterfaceSubClass 1 bInterfaceProtocol 32 ** UNRECOGNIZED: 09 24 01 00 02 0a ae 00 01 ...
This looks like it's mostly standard compliant; please try to add this entry to sound/usb/quirks-table.h:
{ USB_DEVICE(0x, 0x), .driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) { .vendor_name = "M-Audio", .product_name = "MidiSport 2x4", .ifnum = QUIRK_ANY_INTERFACE, .type = QUIRK_COMPOSITE, .data = & (const struct snd_usb_audio_quirk[]) { { .ifnum = 1, .type = QUIRK_AUDIO_STANDARD_MIXER }, { .ifnum = 2, .type = QUIRK_MIDI_STANDARD_INTERFACE }, { .ifnum = 3, .type = QUIRK_AUDIO_STANDARD_INTERFACE }, { .ifnum = 4, .type = QUIRK_AUDIO_STANDARD_INTERFACE }, { .ifnum = -1 } } } }
Transfer Type Isochronous Synch Type Asynchronous Usage Type Implicit feedback Data
Playback is likely to be not correctly synchronized.

Clemens/Daniel,
Does this seem more complete given that DFU and Midi are Class compliant
my guess at the interface purposes from David's post are:
Interface 0 is a DFU firmware upgrade // looks usb class compliant. Interface 1 is really custom (perhaps some sort of custom control/management thing tho I would of thought they'd use midi sysex for that) Interface 2 is the midi //looks 100% standards compliant (works?) Interface 3 looks like maybe a usb mixer without a descriptor? but that's a guess. Interface 4 is potentially usb2 audio output // looks similar to the maudioi fast track isosyncronous outputs Interface 5 is potentially usb2 audio input. // ""
So that all said.
can USB_DEVICE_VENDOR_SPEC deal with out of order compliant/quirked interfaces or only sequencial??
Would this look more like it using USB_DEVICE_VENDOR_SPEC?
USB_DEVICE_VENDOR_SPEC(0x0dba, 0xb011), .driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) { .vendor_name = "Digidesign", .product_name = "Eleven Rack", .ifnum = QUIRK_ANY_INTERFACE, .type = QUIRK_COMPOSITE, .data = & (const struct snd_usb_audio_quirk[]) { { .ifnum = 1, .type = QUIRK_IGNORE_INTERFACE },
{ .ifnum = 3, .type = QUIRK_AUDIO_STANDARD_MIXER }, { .ifnum = 4, .type = QUIRK_AUDIO_STANDARD_INTERFACE }, { .ifnum = 5, .type = QUIRK_AUDIO_STANDARD_INTERFACE }, { .ifnum = -1 } } } }
Will a quirk with no usbid work (assuming david didn't edit what clemens posted) ?
My gut feeling is that the mixer is missing all the endpoint and route stuff so we'll need to build a model of the mixer by sniffing the usb.
