hello fellas,

i try to get a UR22 audio interface from steinberg (yamaha hardware) working on my fedora 19 workstation.

$ lsusb
..
Bus 002 Device 003: ID 0499:1509 Yamaha Corp.
..

i discovered a 'solution' (linuxaudio.org mailing list) written by clemens ladish, adding some additional code to sound/usb/quirks-table.h.

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

i've built (../wiki/Building_a_custom_kernel) a new kernel with the edited quirks-table. (btw, is it possible to do such changes without building a new whole kernel?)

but for now, it's still not working and the interface isn't listed

$ cat /proc/asound/cards
 0 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xf7f78000 irq 21
 1 [XFi            ]: SB-XFi - Creative X-Fi
                      Creative X-Fi 20K1 Unknown
 2 [Generic        ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xfebbc000 irq 42

did i something wrong yet? did i forgot some steps? cause this steps should work - depending on different answers on ladishs post.

for now, thanks for your time and i hope someone can help me!
