ReSpeaker Mic Array v2 dies

We have now three ReSpeaker Mic Array v2.0 and two of three are death after using it on my Laptop (Win10, USB 3.0).

One PCB doesn’t appear in the device manager and the second one has empty VID/PID.

Does someone use the PCB with Win 10 and USB 3.0?

Hi there

it is quite strange, my PC is win10 and USB3.0. but it works well. If the PC can not detect it, we suspect the XMOS is bad. please drop mail to and we will follow up. thanks.
