Sorry, for waiting this long to post this problem, I thought it would be dealt with this week, but since it wasn't better to report it now. I hope this is the right mailing list for this particular problem. I am running FreeBSD 9.1-STABLE and using Logitech Webcam C525. I it's not listed amongst the supported hardware, but it was working perfectly until the updates that came this Sunday, 2013-05-12. The problem I'm getting is this: I keep getting this error message from the kernel, if I'm using 9.1-STABLE r250707 ... pcm6: detached ugen7.2: <vendor 0x046d> at asbus7 uaudio0: <vendor 0x046d HD Webcam C525, class 239/2, rev 2.00/0.10, addr 2> on usbus7 uaudio0: No playback. uaudio0: Record: 48000 Hz, 1 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record: 32000 Hz, 1 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record: 24000 Hz, 1 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record: 16000 Hz, 1 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio: No MIDI squencer. pcm6: <USB audio> on uaudio0 uaudio0: No HID volume keys found. ugen7.2: <vendor 0x046d> at usbus7 (disconnected) uaudio0: at uhub7, port4, addr 2 (disconnected) pcm6: detached ... This message is displayed periodically "ad infinitum" or at least until I unplug the webcam. It stays this way, even if I use the GENERIC kernel. In a "healthy" case, revision 250508, kernel message upon plugging the webcam, is ... ugen7.2: <vendor 0x046d> at usbus7 uaudio0: <vendor 0x046d HD Webcam C525, class 239/2, rev 2.00/1.00, addr2> on usbus7 uaudio: No playback. uaudio: Record: 48000 Hz, 1 ch, 16 bit S-LE PCM format, 2x8ms buffer. uaudio: No MIDI sequencer. pcm6: <USB audio> on uaudio0 uaudio0: No HID volume keys found. And there it stops, and the webcam works in Skype.
Are you able to narrow down the specific commit along 9-stable that broke it? Thanks!

I tried # svn diff -r 250560:250561 /usr/src | less to see if I could localize the problem even further, but there are a lot of changes so I don't know where it could go wrong, since I'm not the one who wrote it. I am looking forward to your fast reply, Jo?e
'ola! Cool, you've nailed it down to a specific revision. Can you create a PR (www.freebsd.org/send-pr.html) with all of this information? Hans/USB folk - here's an interesting problem.
