--- Comment #28 from J.R. Oldroyd <f...@opal.com> --- Well, the case isn't solved at all! Clearly buying a different device that is known to work is one solution, and I am probably going to do that to save time. However, we know that the "pactl exit" hack (with the broken close() code in the driver) will make this device work perfectly. So there is a software solution waiting to be found that would let FreeBSD support this device. It turns out that I missed something. I have provided the uaudio info from the log when this device is connected. After the Windows test, I happened to be watching the log as I reconnected the device to FreeBSD. There is more to this device than just the uaudio part: kernel: ugen0.2: <vendor 0x0a12 product 0x4010> at usbus0 kernel: uhub1 on uhub0 kernel: uhub1: <vendor 0x0a12 product 0x4010, class 9/0, rev 2.00/18.65, addr 17> on usbus0 kernel: uhub1: 4 ports with 0 removable, bus powered kernel: ugen0.3: <vendor 0x0b0e BTV5.2> at usbus0 kernel: uaudio0 on uhub1 kernel: uaudio0: <vendor 0x0b0e BTV5.2, class 0/0, rev 2.00/1.12, addr 18> on usbus0 kernel: uaudio0: Play[0]: 48000 Hz, 2 ch, 16-bit S-LE PCM format, 2x4ms buffer. (selected) kernel: uaudio0: Record[0]: 16000 Hz, 1 ch, 16-bit S-LE PCM format, 2x4ms buffer. (selected) kernel: uaudio0: No MIDI sequencer. kernel: pcm2 on uaudio0 kernel: uaudio0: HID volume keys found. There is also a 0a12:4010 hub device which turns out to be a "Cambridge Silicon Radio, Ltd" hub, or possibly a Chinese-made device squatting on this USB ID. Searching this ID finds various pages saying things like devices with this ID are known to report wrong parameters or report support for USB commands that aren't actually supported. I also find patches for Linux adding some quirks to work around some of these problems. I will likely move to the known-working Jabra solution myself. Debugging this will be for another day when I have more time. -- You are receiving this mail because: You are the assignee for the bug.
