Hi, I've got a USB audio device that identifies itself in dmesg in 8.0- RELEASE like so: ugen6.2: <Thomson multimedia, Inc.> at usbus6 uaudio0: <Thomson multimedia, Inc. Lyra Wireless 2.0.00, class 0/0, rev 1.00/10.00, addr 2> on usbus6 uaudio0: No playback! uaudio0: No recording! uaudio0: No midi sequencer pcm3: <USB audio> on uaudio0 uhid0: <Thomson multimedia, Inc. Lyra Wireless 2.0.00, class 0/0, rev 1.00/10.00, addr 2> on usbus6 The "No playback!" line is the best part, since it's an output-only wireless transmitter. Basically I've got an audio device that neither plays nor records. Fantastic. It played fine in 7.2-RELEASE. I think this may be a similar issue to the one reported originally on this list in May, here: http://lists.freebsd.org/pipermail/freebsd-usb/2009-May/006850.html . That problem was resolved with a patch that was later rescinded as it broke other things. I'm hoping for better luck. Any ideas? Following the suggestions in that thread, I've captured the dmesg output with sysctl hw.usb.uaudio.debug=15, the uaudio related sysctls, and the output of usbconfig -u 6 -a 2 dump_curr_config_desc. I've put them here: http://paste2.org/p/539116 http://paste2.org/p/539119 http://paste2.org/p/539120 In related news, the OSS 4.2 port in the ports tree doesn't seem to build the oss_usb module. Any ideas what's going on with this? I'd be interested to try it and see if I got better results. Thanks! Todd
