Subject: [PATCH] Add a new USB audio quirk for the NuForce UDH-100 device. Interface 1 does not exist and Interface 0 should be ignored. Before this patch, the device would not show up in /dev/snd (and dmesg showed Error -5 from the snd-alsa-usb module); after this patch, the device shows up correctly in /dev/snd and ALSA/Pulseaudio can access it.
