在Mono中使用USB设备

using System;
using System.IO.Ports;

namespace MonoUSBExample
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] ports = SerialPort.GetPortNames();
            Console.WriteLine("Available ports:");
            foreach (string port in ports)
            {
                Console.WriteLine(port);
            }

            SerialPort serialPort = new SerialPort("/dev/ttyUSB0", 9600);
            serialPort.Open();

            serialPort.Write("Hello, World!");
            Console.WriteLine("Data sent to USB device.");

            string dataReceived = serialPort.ReadLine();
            Console.WriteLine("Data received from USB device: " + dataReceived);

            serialPort.Close();
        }
    }
}
