It detects it correct as you can see in the dmesg-log below. The driver also creates a mixer device (mixer3 in my case) However - it does not create a additional pcm/dsp device to get the actual sound data in and out. The device worked for me in 8.0 versions of BSD without problems. -------------:<-------------- ugen0.2: <vendor 0x0d8c> at usbus0 uaudio0: <vendor 0x0d8c USB Sound Device, class 0/0, rev 1.10/0.10, addr 2> on usbus0 uaudio0: Play: 48000 Hz, 2 ch, 16-bit S-LE PCM format uaudio0: Record: 48000 Hz, 2 ch, 16-bit S-LE PCM format uaudio0: No midi sequencer pcm2: <USB audio> on uaudio0 uhid2: <vendor 0x0d8c USB Sound Device, class 0/0, rev 1.10/0.10, addr 2> on usbus0 -------------:<-------------- >How-To-Repeat: Attach a device supported by uaudio and look for a new created dsp device >Fix: >Release-Note: >Audit-Trail: >Unformatted:
