I got one of these rather nice USB conference phones. It works fine with Windows/Mac. ALSA gives the following errors:
[336517.162535] usb 1-1.1: SerialNumber: 0023781E0530x010100 [336517.172419] ALSA sound/usb/stream.c:176 10:1:1 : no or invalid class specific endpoint descriptor [336517.177029] ALSA sound/usb/stream.c:176 10:2:1 : no or invalid class specific endpoint descriptor [336517.183248] ALSA sound/usb/mixer.c:795 2:0: cannot get min/max values for control 2 (id 2) [336517.183350] ALSA sound/usb/mixer.c:795 5:0: cannot get min/max values for control 2 (id 5) [336517.236151] input: Jabra SPEAK 410 USB as /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.1/1-1.1:1.3/input/input13
The microphone and other features are fine, but there is no playback.
I hope I've attached all possible details about this device, but if there is anything I've missed out, please let me know.
Rich.
