How to Get Information About Recently Connected Usb Device

How do I get information about recently connected USB device?

The Win32_DeviceChangeEvent reports just the type of event that occurred and the Time of the event (uint64, representing 100-nanosecond intervals after January 1, 1601, UTC). No that much useful if you also want to know what arrived or was removed.

I suggest to use instead the WqlEventQuery class, setting its EventClassName to __InstanceOperationEvent.

This system class provides a TargetInstance property the can be cast to a ManagementBaseObject, the full management object that also provides base information on the Device that generated the event.

This information includes (besides the friendly name of the Device) the PNPDeviceID, which can be used to build other queries to further inspect the Device referenced.

The WqlEventQuery's Condition property can be set here to TargetInstance ISA 'Win32_DiskDrive'.

It can be set to any other Win32_ class of interest.

Setup the event listener (local machine):

(The event handler is called DeviceChangedEvent)

var query = new WqlEventQuery() {
    EventClassName = "__InstanceOperationEvent",
    WithinInterval = new TimeSpan(0, 0, 3),
    Condition = @"TargetInstance ISA 'Win32_DiskDrive'"
};

var scope = new ManagementScope("root\\CIMV2");
using (var moWatcher = new ManagementEventWatcher(scope, query))
{
    moWatcher.Options.Timeout = ManagementOptions.InfiniteTimeout;
    moWatcher.EventArrived += new EventArrivedEventHandler(DeviceChangedEvent);
    moWatcher.Start();
}

The event handler receives, in e.NewEvent.Properties["TargetInstance"], the Management Object representing a Win32_DiskDrive class.

See the Docs about the properties directly available here.

The __InstanceOperationEvent derived classes of interest, reported by the e.NewEvent.ClassPath.ClassName, can be:

__InstanceCreationEvent: A new Device arrival has been detected.

__InstanceDeletionEvent: A Device removal has been detected.

__InstanceModificationEvent: An existing device has been modified in some way.

Note that the event is raised in a secondary thread, we need to BeginInvoke() the UI thread to update the UI with the new information.

▶ You should avoid Invoke() here, because it's synchronous: it will block the handler until the method completes. Also, in this context, a dead-lock is not exactly a remote possibility.

See here: Get serial number of USB storage device for a class that provides most of the information available about a device (the information is filtered to show USB devices only, but the filter can be removed).

private void DeviceChangedEvent(object sender, EventArrivedEventArgs e)
{
    using (var moBase = (ManagementBaseObject)e.NewEvent.Properties["TargetInstance"].Value)
    {
        string oInterfaceType = moBase?.Properties["InterfaceType"]?.Value.ToString();
        string devicePNPId = moBase?.Properties["PNPDeviceID"]?.Value.ToString();
        string deviceDescription = moBase?.Properties["Caption"]?.Value.ToString();
        string eventMessage = $"{oInterfaceType}: {deviceDescription} ";

        switch (e.NewEvent.ClassPath.ClassName)
        {
            case "__InstanceDeletionEvent":
                eventMessage += " removed";
                BeginInvoke(new Action(() => UpdateUI(eventMessage)));
                break;
            case "__InstanceCreationEvent":
                eventMessage += "inserted";
                BeginInvoke(new Action(() => UpdateUI(eventMessage)));
                break;
            case "__InstanceModificationEvent":
            default:
                Console.WriteLine(e.NewEvent.ClassPath.ClassName);
                break;
        }
    }
}

private void UpdateUI(string message)
{
   //Update the UI controls with information provided by the event
}

Getting all available information about connected USB devices in windows and NET

The Properties collection property will contain all of the properties you can access.

Get List of connected USB Devices

Add a reference to System.Management for your project, then try something like this:

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; }
    public string Description { get; private set; }
  }
}

Getting location information of the connected USB device

Are you looking for that :

Get-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Enum\USB\VID_03F0&PID_1F1D\5&3aded796&0&2' -Name LocationInformation

PSPath              : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_03F0&PID_1F1D\5&3aded796&0&2
PSParentPath        : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_03F0&PID_1F1D
PSChildName         : 5&3aded796&0&2
PSDrive             : HKLM
PSProvider          : Microsoft.PowerShell.Core\Registry
LocationInformation : Port_#0002.Hub_#0004

Or

(Get-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Enum\USB\VID_03F0&PID_1F1D\5&3aded796&0&2' -Name LocationInformation).LocationInformation
Port_#0002.Hub_#0004

---

You can get the connected devices using :

Get-WmiObject Win32_USBHub

---

You just need to join the two results for exemple for my hard drive :

$PnpdeviceId = (gwmi win32_USBHub | where { $_.name -like '*stockage*'}).PNPDeviceID
(Get-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Enum\$PnpdeviceId" -Name LocationInformation).LocationInformation
