Haven't tested recording yet. /dev/sndstat now says: pcm1: <USB Audio> at ? kld snd_uaudio (1p/1r/1v channels duplex default) mode 1:(output) 2ch, 24/24bit, pcm, 48001-96000Hz mode 3:(output) 2ch, 16/16bit, pcm, 8000-48000Hz mode 1:(input) 2ch, 24/24bit, pcm, 48001-96000Hz mode 2:(input) 2ch, 24/24bit, pcm, 8000-48000Hz mode 3:(input) 2ch, 16/16bit, pcm, 8000-48000Hz I'm still looking for a better method than unloading usb to get the device attached.
