-/* This example demonstrate HID Generic raw Input & Output.
- * It will receive data from Host (In endpoint) and echo back (Out endpoint).
- * HID Report descriptor use vendor for usage page (using template TUD_HID_REPORT_DESC_GENERIC_INOUT)
- *
- * There are 2 ways to test the sketch
- * 1. Using nodejs
- * - Install nodejs and npm to your PC
- *
- * - Install excellent node-hid (https://github.com/node-hid/node-hid) by
- * $ npm install node-hid
- *
- * - Run provided hid test script
- * $ node hid_test.js
- *
- * 2. Using python
- * - Install `hid` package (https://pypi.org/project/hid/) by
- * $ pip install hid
- *
- * - hid package replies on hidapi (https://github.com/libusb/hidapi) for backend,
- * which already available in Linux. However on windows, you may need to download its dlls from their release page and
- * copy it over to folder where python is installed.
- *
- * - Run provided hid test script to send and receive data to this device.
- * $ python3 hid_test.py
