-# USB Host Class driver test project
-Main purpose of this application is to test the USB Host Class drivers.
-
-## CDC-ACM driver
-
-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.
-
-## MSC driver
-
-Basic functionality such as MSC device install/uninstall, file operatons, 
-raw access to MSC device and sudden disconnect is tested.
-
-### Hardware Required
-
-This test requires two ESP32-S2/S3 boards with a interconnected USB perpherals,
-one acting as host running MSC host driver and another MSC device driver (tinyusb).
