尝试在项目中添加对System.Management的引用，然后您可以进行如下试验：

namespace ConsoleApplication1 {
    using System;
    using System.Collections.Generic;
    using System.Management; // need to add System.Management to your project references.

    class Program {
        static void Main(string[] args) {
            var usbDevices = GetUSBDevices();

            foreach(var usbDevice in usbDevices) {
                Console.WriteLine("Device ID: {0}, PNP Device ID: {1}, Description: {2}", usbDevice.DeviceID, usbDevice.PnpDeviceID, usbDevice.Description);
            }

            Console.Read();
        }

        static List < USBDeviceInfo > GetUSBDevices() {
            List < USBDeviceInfo > devices = new List < USBDeviceInfo > ();

            ManagementObjectCollection collection;
            using(var searcher = new ManagementObjectSearcher(@"Select * From Win32_USBHub"))
            collection = searcher.Get();

            foreach(var device in collection) {
                devices.Add(new USBDeviceInfo((string) device.GetPropertyValue("DeviceID"), (string) device.GetPropertyValue("PNPDeviceID"), (string) device.GetPropertyValue("Description")));
            }

            collection.Dispose();
            return devices;
        }
    }

    class USBDeviceInfo {
        public USBDeviceInfo(string deviceID, string pnpDeviceID, string description) {
            this.DeviceID = deviceID;
            this.PnpDeviceID = pnpDeviceID;
            this.Description = description;
        }
        public string DeviceID {
            get;
            private set;
        }
        public string PnpDeviceID {
            get;
            private set;

谢谢这部分是有效的，我怎样才能得到控制面板中指定的模型名称？模型？就像在设备模型中一样？我试过了，不幸的是输出与控制面板中的显示方式不同，知道如何获得显示名称吗？谢谢。这部分是有效的，我怎样才能得到控制面板中指定的模型名称？模型？就像在设备模型中一样？我试过这个，不幸的是输出与控制面板中的显示方式不同，知道如何获得显示名称吗？
