How Can I Programmatically Enumerate Connected USB Devices in Windows?

The USB device enumerated in Windows

The complete list of USB devices connected to the Windows computer is essential for system monitoring, hardware management and debugging. To this end, the Windows Management Specification (WMI) provides a powerful solution.

Use System.management to name the name space

First, the project contains a reference to the system.management. This naming space enables your code to interact with WMI. WMI is a key component for querying system information.

Query the USB hub device

The key to identifying the USB device is to query Win32_usbHub instance. These objects represent the physical or virtual hub on the USB bus hierarchy, which provides detailed information about the connected device. Query equipment attributes

After obtaining a list of USBHUB objects, you can continue to check its attribute values, such as Deviceid, PNPDEVICEID (the only hardware identifier) ​​and Description (the name of the user's readable device).

Fill the USBDeviceInfo class

In order to organize the data retrieved, consider creating a custom class called USBDEVICEINFO. This should include the attributes of DeviceID, PNPDeviceid, and Description, so that you can encapsulate important device attributes.

Extracting equipment information

instantiated USBDEVICEINFO class, and fills the corresponding data by extracting the corresponding data from each USBHUB object in the set to fill its attributes. This allows you to build a structured list of all detected USB devices.

code example

The following code fragment provides an example of explanation to explain how to retrieve and process USB device information in C#:

By using WMI and following these steps, you can effectively extract and enumerate the USB device connected to Windows computers to provide you with a reliable method to monitor and manage USB hardware.

Mastering Polymorphism in C  : A Deep DiveMastering Polymorphism in C : A Deep DiveMay 14, 2025 am 12:13 AM

Mastering polymorphisms in C can significantly improve code flexibility and maintainability. 1) Polymorphism allows different types of objects to be treated as objects of the same base type. 2) Implement runtime polymorphism through inheritance and virtual functions. 3) Polymorphism supports code extension without modifying existing classes. 4) Using CRTP to implement compile-time polymorphism can improve performance. 5) Smart pointers help resource management. 6) The base class should have a virtual destructor. 7) Performance optimization requires code analysis first.

C   and XML: Integrating Data in Your ProjectsC and XML: Integrating Data in Your ProjectsMay 10, 2025 am 12:18 AM

Integrating XML in a C project can be achieved through the following steps: 1) parse and generate XML files using pugixml or TinyXML library, 2) select DOM or SAX methods for parsing, 3) handle nested nodes and multi-level properties, 4) optimize performance using debugging techniques and best practices.

Using XML in C  : A Guide to Libraries and ToolsUsing XML in C : A Guide to Libraries and ToolsMay 09, 2025 am 12:16 AM

XML is used in C because it provides a convenient way to structure data, especially in configuration files, data storage and network communications. 1) Select the appropriate library, such as TinyXML, pugixml, RapidXML, and decide according to project needs. 2) Understand two ways of XML parsing and generation: DOM is suitable for frequent access and modification, and SAX is suitable for large files or streaming data. 3) When optimizing performance, TinyXML is suitable for small files, pugixml performs well in memory and speed, and RapidXML is excellent in processing large files.

C# and C  : Exploring the Different ParadigmsC# and C : Exploring the Different ParadigmsMay 08, 2025 am 12:06 AM

The main differences between C# and C are memory management, polymorphism implementation and performance optimization. 1) C# uses a garbage collector to automatically manage memory, while C needs to be managed manually. 2) C# realizes polymorphism through interfaces and virtual methods, and C uses virtual functions and pure virtual functions. 3) The performance optimization of C# depends on structure and parallel programming, while C is implemented through inline functions and multithreading.

C   XML Parsing: Techniques and Best PracticesC XML Parsing: Techniques and Best PracticesMay 07, 2025 am 12:06 AM

The DOM and SAX methods can be used to parse XML data in C. 1) DOM parsing loads XML into memory, suitable for small files, but may take up a lot of memory. 2) SAX parsing is event-driven and is suitable for large files, but cannot be accessed randomly. Choosing the right method and optimizing the code can improve efficiency.

C is widely used in the fields of game development, embedded systems, financial transactions and scientific computing, due to its high performance and flexibility. 1) In game development, C is used for efficient graphics rendering and real-time computing. 2) In embedded systems, C's memory management and hardware control capabilities make it the first choice. 3) In the field of financial transactions, C's high performance meets the needs of real-time computing. 4) In scientific computing, C's efficient algorithm implementation and data processing capabilities are fully reflected.

Debunking the Myths: Is C   Really a Dead Language?Debunking the Myths: Is C Really a Dead Language?May 05, 2025 am 12:11 AM

C is not dead, but has flourished in many key areas: 1) game development, 2) system programming, 3) high-performance computing, 4) browsers and network applications, C is still the mainstream choice, showing its strong vitality and application scenarios.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
