I’m trying to have the Ubuntu 18.04 system recognize the microphone array when connected via USB, but it doesn’t even recognize it.
I followed the instructions shown by the following wiki
and the way that it was advertised, one could simply plug and get it running. However, when trying to connect it to my Ubuntu 18.04, the computer doesn’t even recognize the microphone.
I’ve seen that when other people plug it in and run the command below, they obtain the following results
<br/>
$ arecord -l<br/>
<br/>

However, when I run it, I obtain the following results

$ arecord -l <br/>

This tells me that the microphone array is not being recognized. When I try to see the USB devices, I obtain:
<br/>
$ lsusb <br/>

What have I tried
I have tried playing around with the ALSA Mixer, and nothing was recognized
I have tried the Gnome System Settings, and nothing was recognized
By following the link above, I followed the instructions by cloning the repo usb_4_mic_array and tried to do a Device Firmware Update by running
$ python dfu.py --download 6_channels_firmware.bin
and it said that No DFU is found
I have tried using the following repo
https://github.com/respeaker/mic_array_dfu
and it returned
<br/>
VID = 0x1d6b, PID = 0x3, BCDDevice: 0x500<br/>
VID = 0x138a, PID = 0x97, BCDDevice: 0x164<br/>

Could not find/open device<br/>
Verdict
There are people who have gotten it to work
Most people are using it for RPi, but I am more interested in getting it to work on my local machine, and I think this is a system problem, and I have no idea how to proceed.
Thank you in advance!
