Hi @xiongyihui

We're trying to get ReSpeaker Mic Array with 7 PDM Mics work on raspbian 9.

So, we installed fresh raspbian, plugged ReSpeaker.

pi@raspberrypi:~/mic_array $ arecord -l
**** List of CAPTURE Hardware Devices ****
pi@raspberrypi:~/mic_array $ lsusb

We can't see any recording hardware / usb devices. Running mic_array repository script gives us:

As you told to someone we tried to change firmware

dfu command output ``` pi@raspberrypi:~/mic_array_dfu $ sudo ./dfu --download respeaker_mic_array_8ch_raw.bin VID = 0x46d, PID = 0xc06c, BCDDevice: 0x6300 VID = 0x46d, PID = 0xc52b, BCDDevice: 0x2400 VID = 0x424, PID = 0xec00, BCDDevice: 0x200 VID = 0x424, PID = 0x9514, BCDDevice: 0x200 VID = 0x1d6b, PID = 0x2, BCDDevice: 0x409 Could not find/open device ```

So we have Could not find/open device, the same as here: respeaker/mic_array_dfu#3
However, we already run this command with sudo and still have the problem.

In short:
We can't see the ReSpeaker in lsusb, arecord -l, python mic_array.py. Tried to update firmware, but didn't succeed. Also tried to execute different commands from github issues that's indirectly related to our problem - still nothing.

Please, can you tell us what to try? Simply need to capture audio with pyaudio through ReSpeaker.

Thank you very much.

Did the mic arrary power on?
Maybe try another usb cable
and can you post the log of dmesg

Hi @xiongyihui!

Thank you very much for your answer. All problems were in the USB cable. We replaced it and everything is working great.

Thanks!

@fahrenq Do you need to update firmware for 8 channel data???

peterlundblad commented

Hello,
I'm also having issues connect my mic-array. It powers on, but my pi won't recognize it. I've tried a few different cables.

Thanks in advance!
