Mic Array: USB Audio Device - No Devices connected
Posted: Tue Sep 12, 2017 6:43 pm
Hi,
I'm having trouble getting the XCORE Array Microphone XK-USB-MIC-UF216 to function. My goal is to use it as a 7 element usb mic array.
I bought the XCore Array Microphone from digikey and followed the instructions here : https://www.xmos.com/support/boards?product=20258. I built app_usb_aud_mic_array application for the 2i8o2 target. I made no modifications to the makefile. There were some build warnings out of the box (see attached build log). I have installed the Thesycon evaluation driver.
However, when I attach the mic array via USB to my Windows 10 PC, the mic array is not detected. The TUSBAudio Control Panel reports USB Audio Device No devices connected and nothing shows up in the device manager. The LEDs do toggle when I press the A button so I am fairly certain that I flashed the array correctly.
I have also tested on an embedded Linux platform with USB Audio Class 2 support with the same negative result.
Also, I have another XMOS array microphone that is fresh out of the box and hasn't been reflashed. That device does not show up in TUSBAudio Control Panel or device manager either. It behaves differently from the flashed version the LEDs are always on and pressing the A button has no visible effect.
Any hints on how to proceed or troubleshoot my setup.
