To see the devices I was interested in, I had replace <code>Win32_USBHub</code> by <code>Win32_PnPEntity</code> in Adel Hazzah's code, based on <a href="https://stackoverflow.com/questions/22235656/how-do-i-query-for-usb-devices-not-listed-in-usb-root-hub">this post</a>. This works for me:

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

 Console.Read();
 }

 static List&lt;USBDeviceInfo&gt; GetUSBDevices()
 {
 List&lt;USBDeviceInfo&gt; devices = new List&lt;USBDeviceInfo&gt;();

 ManagementObjectCollection collection;
 using (var searcher = new ManagementObjectSearcher(@"Select * From Win32_PnPEntity"))
 collection = searcher.Get(); 

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

If you change the ManagementObjectSearcher to the following:

<pre><code>ManagementObjectSearcher searcher = 
 new ManagementObjectSearcher("root\\CIMV2", 
 @"SELECT * FROM Win32_PnPEntity where DeviceID Like ""USB%"""); 
</code></pre>

So the "GetUSBDevices() looks like this"

<pre><code>static List&lt;USBDeviceInfo&gt; GetUSBDevices()
{
 List&lt;USBDeviceInfo&gt; devices = new List&lt;USBDeviceInfo&gt;();

 ManagementObjectCollection collection;
 using (var searcher = new ManagementObjectSearcher(@"SELECT * FROM Win32_PnPEntity where DeviceID Like ""USB%"""))
 collection = searcher.Get();

 (string)device.GetPropertyValue("PNPDeviceID"),
 (string)device.GetPropertyValue("Description")
 ));
 }

 collection.Dispose();
 return devices;
}
</code></pre>

}

Your results will be limited to USB devices (as opposed to all types on your system)

Adel Hazzah's <a href="https://stackoverflow.com/a/3331509/2939139">answer</a> gives working code, <a href="https://stackoverflow.com/questions/3331043/get-list-of-connected-usb-devices#comment62858210_3331509">Daniel Widdis's</a> and <a href="https://stackoverflow.com/users/372983/nedko">Nedko's</a> comments mention that you need to query Win32_USBControllerDevice and use its Dependent property, and Daniel's <a href="https://stackoverflow.com/a/37604994/2939139">answer</a> gives a lot of detail without code.

Here's a synthesis of the above discussion to provide working code that lists the directly accessible PNP device properties of all connected USB devices:

 foreach (var property in usbDevice.Properties)
 {
 Console.WriteLine(string.Format("{0}: {1}", property.Name, property.Value));
 }
 Console.WriteLine("------------------");
 }
 }

 public static IList&lt;ManagementBaseObject&gt; GetUsbDevices()
 {
 IList&lt;string&gt; usbDeviceAddresses = LookUpUsbDeviceAddresses();

 List&lt;ManagementBaseObject&gt; usbDevices = new List&lt;ManagementBaseObject&gt;();

 foreach (string usbDeviceAddress in usbDeviceAddresses)
 {
 // query MI for the PNP device info
 // address must be escaped to be used in the query; luckily, the form we extracted previously is already escaped
 ManagementObjectCollection curMoc = QueryMi("Select * from Win32_PnPEntity where PNPDeviceID = " + usbDeviceAddress);
 foreach (ManagementBaseObject device in curMoc)
 {
 usbDevices.Add(device);
 }
 }

 return usbDevices;
 }

 public static IList&lt;string&gt; LookUpUsbDeviceAddresses()
 {
 // this query gets the addressing information for connected USB devices
 ManagementObjectCollection usbDeviceAddressInfo = QueryMi(@"Select * from Win32_USBControllerDevice");

 List&lt;string&gt; usbDeviceAddresses = new List&lt;string&gt;();

 foreach(var device in usbDeviceAddressInfo)
 {
 string curPnpAddress = (string)device.GetPropertyValue("Dependent");
 // split out the address portion of the data; note that this includes escaped backslashes and quotes
 curPnpAddress = curPnpAddress.Split(new String[] { "DeviceID=" }, 2, StringSplitOptions.None)[1];

 usbDeviceAddresses.Add(curPnpAddress);
 }

 return usbDeviceAddresses;
 }

 // run a query against Windows Management Infrastructure (MI) and return the resulting collection
 public static ManagementObjectCollection QueryMi(string query)
 {
 ManagementObjectSearcher managementObjectSearcher = new ManagementObjectSearcher(query);
 ManagementObjectCollection result = managementObjectSearcher.Get();

 managementObjectSearcher.Dispose();
 return result;
 }

 }

}

You'll need to add exception handling if you want it. Consult Daniel's answer if you want to figure out the device tree and such.
