ReSpeaker v2 Mic Array, Cant find device via USB on both Ubuntu18 and Win7

[MAXycccc]

Hi
I'm dealing with sound tracking, but my Mic Array cant be detected on Ubuntu18 and Win7

I tried commond lsusb on Ubuntu, no information

Also I tried the related Python scripts, but it sitll cant find the device

However, the blue led works well, and the sound traking works well too when I connect to my PC (I knocked the desk, the closest light turn to green)

Anyone has some idea? I only get the performance, but cant go further coding issues

Did you try from the instructions:

ls /dev/ttyACM*, you should get /dev/ttyACMx where x will vary depending on which USB port you used.

E.g. if you do an ls -la /dev/tty*, does it show anything? For me (on Ubuntu 18) I see /dev/ttyACM0 and was able to successfully connect to it right off the bat.
