Hi,
Today I've tested my M-Audio Transit USB sound card with the new usb stack. It
requires to download a firmware which works with some minor problems.
It's recognized as follows:
ugen0.2: <Unknown> at usbus0
<firmware upload is done here>
ugen0.2: <M-Audio> at usbus0
uaudio0: <Transit USB> on usbus0
uaudio0: Play: 96000 Hz, 2 ch, 24-bit S-LE PCM format
uaudio0: Record: 96000 Hz, 2 ch, 24-bit S-LE PCM format
uaudio0: No midi sequencer
pcm1: <USB audio> on uaudio0
I don't get any sound though. mixer lists vol, pcm and mic. If I turn up mic
to 100 there's some output (mostly static). So something goes wrong here.
With the old uaudio driver
#define UAUDIO_MULTIPLE_ENDPOINTS
needs to be undefined to get the card working (if this gives any clue)
Additionaly mixer lists a 'speaker' device which need to be turned on to get
sound.
