Please try adding the following entry somewhere in sound/usb/quirks-table.h:
{
USB_DEVICE(0x0499, 0x1509),
.driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) {
/* .vendor_name = "Yamaha", */
/* .product_name = "Steinberg UR22", */
.ifnum = QUIRK_ANY_INTERFACE,
.type = QUIRK_COMPOSITE,
.data = (const struct snd_usb_audio_quirk[]) {
{
.ifnum = 1,
.type = QUIRK_AUDIO_STANDARD_INTERFACE
},
{
.ifnum = 2,
.type = QUIRK_AUDIO_STANDARD_INTERFACE
},
{
.ifnum = 3,
.type = QUIRK_MIDI_YAMAHA
},
{
.ifnum = 4,
.type = QUIRK_IGNORE_INTERFACE
},
{
.ifnum = -1
}
}
}
},
Regards,
Clemens
