Detailed Description
Configuration structure for USB Audio, inheriting from AudioInfo.
This struct extends AudioInfo and adds USB-specific configuration parameters such as endpoint addresses, buffer sizes, and feature flags for USB audio streaming.
The documentation for this struct was generated from the following file:
- src/AudioTools/Sandbox/USB/USBAudioConfig.h
