+It tests basic functionality of the driver like open/close/read/write operations,
+advanced features like CDC control request, multi-threaded or multi-device access,
+as well as reaction to sudden disconnection and other error states.
+
+### Hardware Required
+
+This test expects that TinyUSB dual CDC device with VID = 0x303A and PID = 0x4002
+is connected to the USB host.

+### Hardware Required
+
+This test requires two ESP32-S2/S3 boards with a interconnected USB peripherals,
+one acting as host running MSC host driver and another MSC device driver (tinyusb).
