Setting vendor=1 doesn't load the snd-motu-avb #1

Open magoostus opened 3 years ago

magoostus commented 3 years ago

it seems that setting "vendor=1" module parameter doesn't load up snd-motu-avb like it should

I've also tried setting the CURL command which the stage-b16 accepts, but it doesn't seem to make a difference

Where as "vendor=0" loads up like this correctly

I'm trying this on a raspi4b with kernel 5.11.0-1007-raspi on ubuntu 21.04

vendor mode requires a kernel patch that disables the duplicate endpoint nonsense.

Modify in drivers/usb/core/config.c the function config_endpoint_is_duplicate so that it always returns false (just remove everything in that function except the "return false" statement at the end).

You may also want to blacklist the motu in the snd-usb-audio driver.

In sound/usb/card.c modify the function usb_audio_probe:

below:

id = USB_ID(le16_to_cpu(dev->descriptor.idVendor),
            le16_to_cpu(dev->descriptor.idProduct));

add:

    /* blacklist motu */

    if (id == USB_ID(0x07fd, 0x0005))
    return -ENODEV;
