+//! <h1>USB Composite HID Keyboard Mouse Device (usb_dev_chid)</h1>
+//!
+//! This example application turns the evaluation board into a composite USB
+//! keyboard and mouse example using the Human Interface Device class. The
+//! color LCD displays a blank area which acts as a mouse touchpad. The button
+//! on the bottom of the screen acts as a toggle between keyboard and mouse
+//! mode. Pressing it toggles the screen to keyboard mode and allows keys
+//! to be sent to the USB host. The board status LED is used to indicate the
+//! current Caps Lock state and is updated in response to pressing the ``Caps''
+//! key on the virtual keyboard or any other keyboard attached to the same USB
+//! host system.
