A headphone audio fix for the Logitech USB Headset 350
Authored by: gwallace01451 on Nov 18, '05 05:55:12AM

I googled USB 350 Logitech and got:

http://lists.freebsd.org/pipermail/freebsd-multimedia/2005-April/002039.html

with some the text copied below:

3. Is your USB controller ohci or uhci?
uhci has no problem. But ohci has the full duplex problem.
microphone and speaker can't be use simultaneously without full duplex.
Then a USB headset can't be use with ohci.

But if you want to use it as headphone only, or microphone only,
ohci has no problem.

3'.If you want to use microphone and speaker simultaneously with uhci,
you must comment-out below lines
at function uaudio_init_params() in uaudio.c

if ((sc->sc_playchan.pipe != NULL) || (sc->sc_recchan.pipe != NULL))
return (-1);


Now I'm trying to figure out how to implement something 10.4.3.
