Hi,all

I'm trying to use usb-audio device on FreeBSD/Raspberry PI

However I can't use that with below message(I can use that device on FreeBSD/i386).

pcm0: chn_init(pcuaudio_mixer_write_cfg_callback:
m0:play:dsp0.p0) fuaudio_mixer_write_cfg_callback:
ailed: err = 19
puaudio_mixer_write_cfg_callback:
cm0: pcm_chn_create(ua_chan, 1, 0xc10f2400) failed
uaudio_chan_init: endpoint=0x85, speed=48000, iface=2 alt=1
uaudio_chan_init: could not allocate USB transfers!
pcm0: chn_init(pcm0:record:dsp0.r0) failed: err = 19
pcm0: pcm_chn_create(ua_chan, -1, 0xc10f2400) failed

If someone know the reason, please let me to know.
