到System.Management添加引用項目後，引用代碼

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}", usbDevice.DeviceID); 

     } 

     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") 
      )); 
     } 

     collection.Dispose(); 
     return devices; 
    } 
} 

class USBDeviceInfo 
{ 
    public USBDeviceInfo(string deviceID) 
    { 
     this.DeviceID = deviceID; 
    } 
    public string DeviceID { get; private set; } 

} 

}

希望它可以幫助你。
