USB microphone example with USBX

Hi,

Could you please let me know if you’re planning to provide an example of a USB Audio device based on USBX in the near future?

By the way, the ST X-CUBE-AUDIO package is based on TinyUSB that is not officially supported. I’m wondering whether it’s feasible to implement a USB microphone using USBX instead.

Regards.
