// This example runs both host and device concurrently. The USB host looks for
// any HID device with reports that are 8 bytes long and then assumes they are
// keyboard reports. It translates the keypresses of the reports to ASCII and
// transmits it over CDC to the device's host.
// This example runs both host and device concurrently. The USB host receive
// reports from HID device and print it out over USB Device CDC interface.
