Добрый день ! Решил Запустить Raspberry Pi Pico как HID IN/OUT устройство. Написал на C# HID Terminal с использованием библиотеки HIDLibrary. Нашел как идентифицировать свое устройство и запросить данные о нем. Но ни как не могу на Pico передать данные и получить их обратно эхом.

/* This example demonstrate HID Generic raw Input & Output.

*
* 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.
