The Google USB Driver is required for Windows if you want to perform adb debugging with Google devices. Windows drivers for all other devices are provided by the respective hardware manufacturer, as listed in the OEM USB Drivers document. Xiaomi USB Drivers allow you to connect your Phone to a PC, whether it’s a smartphone or a tablet so that the computer can easily recognize the device via the USB port. In this article, We will publish links for Xiaomi USB Drivers to transfer files from Your Phone to your computer or you will be able to update your Xiaomi to latest Android OS. When you connect a USB audio device to a Windows 10 Version 1703-based computer the first time, the operating system detects the device but loads the standard USB audio 2.0 driver (usbaudio2.sys) instead of the specific device driver.

In this topic you'll use the USB User-Mode Driver template provided with Microsoft Visual Studio 2019 to write a user-mode driver framework (UMDF)-based client driver. After building and installing the client driver, you'll view the client driver in Device Manager and view the driver output in a debugger.

UMDF (referred to as the framework in this topic) is based on the component object model (COM). Every framework object must implement IUnknown and its methods, QueryInterface, AddRef, and Release, by default. The AddRef and Release methods manage the object's lifetime, so the client driver does not need to maintain the reference count. The QueryInterface method enables the client driver to get interface pointers to other framework objects in the Windows Driver Frameworks (WDF) object model. Framework objects perform complicated driver tasks and interact with Windows. Certain framework objects expose interfaces that enable a client driver to interact with the framework.

A UMDF-based client driver is implemented as an in-process COM server (DLL), and C++ is the preferred language for writing a client driver for a USB device. Typically, the client driver implements several interfaces exposed by the framework. This topic refers to a client driver-defined class that implements framework interfaces as a callback class. After these classes are instantiated, the resulting callback objects are partnered with particular framework objects. This partnership gives the client driver the opportunity to respond to device or system-related events that are reported by the framework. Whenever Windows notifies the framework about certain events, the framework invokes the client driver's callback, if one is available. Otherwise the framework proceeds with the default processing of the event. The template code defines driver, device, and queue callback classes.

For an explanation about the source code generated by the template, see Understanding the UMDF template code for USB client driver.

Prerequisites

For developing, debugging, and installing a user-mode driver, you need two computers:

A host computer running Windows 7 or a later version of the Windows operating system. The host computer is your development environment, where you write and debug your driver.
A target computer running the version of the operating system that you want to test your driver on, for example, Windows 10, version 1903. The target computer has the user-mode driver that you want to debug and one of the debuggers.

In some cases, where the host and target computers are running the same version of Windows, you can have just one computer running Windows 7 or a later version of the Windows. This topic assumes that you are using two computers for developing, debugging, and installing your user mode driver.

Before you begin, make sure that you meet the following requirements:

Software requirements

Your host computer has Visual Studio 2019.
Your host computer has the latest Windows Driver Kit (WDK) for Windows 10, version 1903.
The kit include headers, libraries, tools, documentation, and the debugging tools required to develop, build, and debug a USB client driver. You can get the latest version of the WDK from How to Get the WDK.
Your host computer has the latest version of debugging tools for Windows. You can get the latest version from the WDK or you can Download and Install Debugging Tools for Windows.
If you are using two computers, you must configure the host and target computers for user-mode debugging. For more information, see Setting Up User-Mode Debugging in Visual Studio.

Hardware requirements

Get a USB device for which you will be writing the client driver. In most cases, you are provided with a USB device and its hardware specification. The specification describes device capabilities and the supported vendor commands. Use the specification to determine the functionality of the USB driver and the related design decisions.

If you are new to USB driver development, use the OSR USB FX2 learning kit to study USB samples included with the WDK. It contains the USB FX2 device and all the required hardware specifications to implement a client driver.

Instructions

Step 1: Generate the UMDF driver code by using the Visual Studio 2019 USB driver template

For instructions about generating UMDF driver code, see Writing a UMDF driver based on a template.

For USB-specific code, select the following options in Visual Studio 2019

In the New Project dialog box, in the search box at the top, type USB.
n the middle pane, select User Mode Driver, USB (UMDF V2).
lick Next.
Enter a project name, choose a save location, and click Create.

The following screen shots show the New Project dialog box for the USB User-Mode Driver template.

This topic assumes that the name of the project is 'MyUSBDriver_UMDF_'. It contains the following files:

Files	Description
Driver.h; Driver.c	Declares and defines a callback class that implements the IDriverEntry interface. The class defines methods that are invoked by the framework driver object. The main purpose of this class is to create a device object for the client driver.
Device.h; Device.c	Declares and defines a callback class that implements the IPnpCallbackHardware interface. The class defines methods that are invoked by the framework device object. The main purpose of this class is to handle events occurring as a result of Plug and Play (PnP) state changes. The class also allocates and initializes resources required by the client driver as long as it is loaded in the system.
IoQueue.h; IoQueue.c	Declares and defines a callback class that implements the IQueueCallbackDeviceIoControl interface. The class defines methods that are invoked by the framework queue object. The purpose of this class is to retrieve I/O requests that are queued in the framework.
Internal.h	Provides common declarations shared by the client driver and user applications that communicate with the USB device. It also declares tracing functions and macros.
Dllsup.cpp	Contains the implementation of the driver module's entry point.
<Project name>.inf	INF file that is required to install the client driver on the target computer.
Exports.def	DEF file that exports the entry point function name of the driver module.

Step 2: Modify the INF file to add information about your device

Before you build the driver, you must modify the template INF file with information about your device, specifically the hardware ID string.

To provide the hardware ID string

Attach your USB device to your host computer and let Windows enumerate the device.
Open Device Manager and open properties
