How Can I List All Connected USB Devices in Windows Using C#?
List connected USB devices in Windows using C#
Question:
How to identify and get information about all USB devices connected to Windows system?
Solution:
By integrating the System.Management namespace into your project, you can retrieve the list of USB devices using the following code:
using System;
using System.Collections.Generic;
using System.Management; // 将 System.Management 添加到您的项目引用中。
public class Program
{
public static void Main(string[] args)
{
var usbDevices = GetUSBDevices();
foreach (var usbDevice in usbDevices)
{
Console.WriteLine(
$"设备 ID：{usbDevice.DeviceID}，PNP 设备 ID：{usbDevice.PnpDeviceID}，描述：{usbDevice.Description}");
}
Console.ReadKey();
}
public static List<USBDeviceInfo> GetUSBDevices()
{
var devices = new List<USBDeviceInfo>();
using (var searcher = new ManagementObjectSearcher(@"Select * From Win32_USBHub"))
using (var collection = searcher.Get())
{
foreach (var device in collection)
{
devices.Add(new USBDeviceInfo(
(string)device.GetPropertyValue("DeviceID"),
(string)device.GetPropertyValue("PNPDeviceID"),
(string)device.GetPropertyValue("Description")
));
}
}
return devices;
}
}
public class USBDeviceInfo
{
public USBDeviceInfo(string deviceID, string pnpDeviceID, string description)
{
DeviceID = deviceID;
PnpDeviceID = pnpDeviceID;
Description = description;
}
public string DeviceID { get; private set; }
public string PnpDeviceID { get; private set; }
public string Description { get; private set; }
}This solution uses the System.Management namespace to access the ManagementObjectSearcher class, allowing you to query the Win32_USBHub class to find USB devices. The code iterates over the returned collection to extract relevant information such as device ID, PNP device ID, and description, providing a complete list of connected USB devices.
