I just bought a digital USB microphone. It looks nice, but I cannot make it work. I use openSuse 12.3. How do I ever know whether my system has the drivers for such and such microphone?The good news it shows in alsamixer as usb microphone. It is set as capture device with full volume, it's listed in arecord --list-devices but still I cannot start recording with `arecord hw:N,M . [ I get mute file -- test.wav ] . From what I understood, the first step should be to disable all third party sound servers (like Pulse-Audio, Xine, Phonon etc.) and try the ALSA way. tom@oberon:~> lsusb Bus 003 Device 002: ID 046d:c044 Logitech, Inc.LX3 Optical Mouse Bus 003 Device 003: ID 062a:0201 Creative LabsDefender Office Keyboard (K7310) S Zodiak KM-9010 Bus 010 Device 002:ID 0d8c:0005 C-Media Electronics, Inc.The arecord --list-devices gives line:  card 1: MICROPHONE [USB MICROPHONE], device 0: USB Audio [USB Audio]   Subdevices: 1/1   Subdevice #0: subdevice #0I tried recording with audacity, but it does not work to no extend.dmesg comand output:[ 4270.201048] usb 10-1: new full-speed USB device number 3 using xhci_hcd[ 4270.247392] usb 10-1: New USB device found, idVendor=0d8c, idProduct=0005[ 4270.247399] usb 10-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3[ 4270.247404] usb 10-1: Product: USB MICROPHONE[ 4270.247408] usb 10-1: Manufacturer: MICE MICROPHONE[ 4270.247411] usb 10-1: SerialNumber: 201308[ 4270.261462] input: MICE MICROPHONE USB MICROPHONE as /devices/pci0000:00/0000:00:07.0/0000:04:00.0/usb10/10-1/10-1:1.2/input/input56[ 4270.261677] hid-generic 0003:0D8C:0005.0004: input,hidraw3: USB HID v1.11 Device [MICE MICROPHONE USB MICROPHONE] on usb-0000:04:00.0-1/input2[ 4270.298216] xhci_hcd 0000:04:00.0: ERROR: unexpected command completion code 0x11.[ 4270.298227] usb 10-1: Not enough bandwidth for altsetting 1[ 4270.306239] ALSA mixer.c:889 10:0: cannot get min/max values for control 2 (id 10)[ 4270.306390] usbcore: registered new interface driver snd-usb-audioWhat does it mean : [ 4270.298216] xhci_hcd 0000:04:00.0: ERROR: unexpected command  completion code 0x11.
