Could not find/open device

[akvkickstart]

I am trying to connect the Mic Array to Raspberry by and I am trying to setup the requirements:

I can see the device being registered to the RPi2b.

But whenever I run: pi@rpigg:~/mic_array_dfu $ ./dfu --download respeaker_mic_array_8ch_raw.bin VID = 0x2886, PID = 0x7, BCDDevice: 0x31 Could not find/open device pi@rpigg:~/mic_array_dfu $

Can you please help with the issue?

[akvkickstart]

I run the following and it also worked:

pi@rpigg:~/mic_array_akv/mic_array $ speaker-test -t wav

speaker-test 1.0.28

Playback device is default Stream parameters are 48000Hz, S16_LE, 1 channels WAV file(s) Rate set to 48000Hz (requested 48000Hz) Buffer size range from 192 to 2097152 Period size range from 64 to 699051 Using max buffer size 2097152 Periods = 4 was set period_size = 524288 was set buffer_size = 2097152 0 - Front Left Time per period = 1.530202 0 - Front Left

I can hear sound from coming from the mic array.

[xiongyihui]

It's not support 48000Hz sample rate. You should use 16000Hz sample rate.

try:

speaker-test -D plughw:1

[akvkickstart]

I got that working, now whenever I run pixel_ring.py, I can see the lights working, but whenever I record, I don't here anything, how can you test the mic array?

Sorry, it's a bug. Need to change with MicArray(16000, 4, 16000 / 4) as mic: to with MicArray(16000, 8, 16000 / 4) as mic:

It's fixed at the latest code.

[prashantmaheshwari94]

I get the same error for this command: pi@raspberrypi:~/mic_array_dfu $ ./dfu --download respeaker_mic_array_8ch_raw.bin VID = 0x2886, PID = 0x7, BCDDevice: 0x31 Could not find/open device

Can anyone help me out here, there isn't much info in this error.

[jacksun101]

I got the same error.

./dfu --download respeaker_mic_array_8ch_raw.bin VID = 0x2886, PID = 0x7, BCDDevice: 0x32 Could not find/open device

[jacksun101]

Oh, I just tried adding "sudo" does the work!

[prashantmaheshwari94]

sudo is required. Run the command with sudo, it will install.

[KillingJacky]

Will close this issue, please open a new issue if you have further questions.

I tried to update the firmware of the ReSpeaker Mic Array v2.0 via

sudo pip install pyusb click git clone https://github.com/respeaker/usb_4_mic_array.git cd usb_4_mic_array sudo python dfu.py --download 6_channels_firmware.bin

First, I also got the error message "ValueError: No DFU device found". When I used another USB cable to try to update the firmware again, the error message disappeared. I am using a HAMA cable (00173625).

See also issue on https://github.com/respeaker/mic_array/issues/22.

I have the same issue WITH sudo. lsusb shows the device as Bus 003 Device 015: ID 2886:0018 Seeed Technology Co., Ltd. ReSpeaker 4 Mic Array (UAC1.0) No other control or dfu device present to point to the ReSpeaker.

On Windows no luck either. Changed the Windows-Drivers to libusb-win32 with zadig. Then tried python dfu.py --download 1_channel_firmware.bin

Error in Line 15, in import usb.core ModuleFoundError: No module named 'usb'.

[RevAngel7]

sudo python3 ./dfu.py --download 1_channel_firmware.bin worked. Seems to be an issue with the executable script, the python file is fine.
