@woodsb,
do not own this mic array but can you attempt to reflash the PCB with the recommended firmware?
Aside from this suggestion:
a) test with other USB cables
b) test with other USB ports
Hoping not but perhaps there is a hardware issue related to in rush current. This is where the USB Vbus rail is spiked with a voltage higher than spec and results in damaging the USB interface. The documentation / errata related to this fault is now posted inside the datasheets. As noted, start with the firmware upgrade and move from there.
Should you replicate the XMOS design, be sure to place in rush current protection onto the Vbus rail that has been discussed on this forum a few times.

Courtesy of the op above...
Here is a compiled version:
Download "sw_usb_audio-[sw]_6.15.2rc1.zip" from the below link
http://www.xmos.com/support/software/uac2
And replace module_xud with the below one
https://drive.google.com/drive/folders/ ... sp=sharing
Then generate "app_usb_aud_mic_array_2i8o2.xe" firmware file with the above combination using xtimecomposer
Now you must be able to find XMOS USB 2.0 audio device on your windows PC.
Note: Makesure you have installed windows driver from the below link (TUSBAudio control panel)

Okay, for me it was the USB cable. Thanks for the tip.
