usb audio and a 1 channel input device

[Kazuhito HONDA]

Hello,

If your USB controller is uhci, you should do 1) below only.
But yours os ohci, you should 1) and 2).

1) Comment out these lines in a function "uaudio_init_params()" of
a file "/usr/src/sys/dev/sound/usb/uaudio.c":
         if ((sc->sc_playchan.pipe != NULL) || (sc->sc_recchan.pipe != NULL))
                return (-1);

2) Use new USB device codes of Hans Petter Selasky
