Changes to the port capability can be indirectly observed by tracing register writes to DWC3_GCTL. However, this requires interpreting the raw value, which is neither intuitive nor precise for debugging. Monitoring these mode changes is essential for resolving issues related to USB role switching and enumeration. Introduce a dedicated trace event to provide a human-readable log when the port capability is configured.
