USB Devices Library (WMI)

Detect And Event All USB Changes and Filter Devices

• Using System.Management Nuget package
• All data get from WMI in system management
• Using Concurrent Collections (System.Collections.Concurrent) : ConcurrentBag, ConcurrentDictionary
• Using setupapi.dll for finding device parent and childs. so you cant use this library remotely such as WMI instructions.
• .Net Core 8.0
• Windows Desktop
• List of USB Devices in pc
• List all of USB device childs
• Supported interfaces:
  • Disk Drive
  • Disk Partition
  • Logical Disk
  • Serial Port
  • Serial Port Configuration
  • Network Adapter
  • Network Adapter Configuration
• Event Types:
  • Connected
  • Disconnected
  • Modified

Usage

1. Create new instance of class USBDevices

   public USBDevices USBDevicesCollection { get; set; }

   USBDevicesCollection = new();

2. By default Connected, Disconnected and Modified events are enabled if you want you can disable each of them by:

   USBDevicesCollection.DisableConnectedEvents();
   USBDevicesCollection.DisableDisconnectedEvents();
   USBDevicesCollection.DisableModifiedEvents();

   or you can enable them by:

   USBDevicesCollection.EnableConnectedEvents();
   USBDevicesCollection.EnableDisconnectedEvents();
   USBDevicesCollection.EnableModifiedEvents();

3. You can set filter list to monitor usb devices. In this case you should enable the filter status by:

   USBDevicesCollection.EnableFilterDevice();

   you can diable filter status by:

   USBDevicesCollection.DisableFilterDevice();

   after enabling, add VID and PID to filter list. You can fillter both of VID & PID or only VID or PID. Such as AddDeviceToFilter("xxxx", "yyyy") or AddDeviceToFilter("xxxx", string.Empty) or AddDeviceToFilter(string.Empty, "yyyy")

   USBDevicesCollection.AddDeviceToFilter("xxxx", "yyyy");

   you can remove from list of filtered devices by RemoveDeviceFromFilter(vid, pid):

   USBDevicesCollection.RemoveDeviceFromFilter("xxxx", "yyyy");

4. Add Events :

   USBDevicesCollection.InitialCollectionsComplete += USBDevicesCollections_InitialCollectionsComplete;
   USBDevicesCollection.CollectionChanged += USBDevicesCollection_CollectionChanged;
   USBDevicesCollection.DeviceChanged += USBDevicesCollections_DeviceChanged;

5. After initial USBDevices class you should start the monitiring by Start():

   USBDevicesCollection.Start();

6. USBDevices class inherited from Concurrent Dictionary. You can access devices list by USBDevicesCollection.Values.
