Similarly, you may ask, what are examples of device drivers?

A device driver is a computer program that controls a particular device that is connected to your computer. Typical devices are keyboards, printers, scanners, digital cameras and external storage devices. Each of these need a driver in order to work properly.

Secondly, why are device drivers required? Purpose of Device Drivers Device drivers are necessary to permit a computer to interface and interact with specific devices. They define the messages and mechanisms whereby the computer (OS and applications) can access the device or make requests for the device to fulfill.

One may also ask, how does a device driver work?

A device driver is a piece of software that allows your computer's operating system to communicate with a hardware device, the driver is written for. When we choose an operation (like Control + P to print a document) on the printer then this command goes to the device driver through the kernel of the operating system.

How do you write a device driver?


  1. Step 1: Generate the KMDF driver code by using the Visual Studio Professional 2019 USB driver template.
  2. Step 2: Modify the INF file to add information about your device.
  3. Step 3: Build the USB client driver code.
  4. Step 4: Configure a computer for testing and debugging.
  5. Step 5: Enable tracing for kernel debugging.

What are the types of device drivers?

Types of Device Drivers
All device drivers can be divided into two main categories: kernel device drivers and user device drivers. Drivers from the first category are loaded with the operating system. They function as a part of your OS after they are loaded in the memory.

Can a device work without device driver?

Without the required device driver, the corresponding hardware device fails to work. A device driver usually communicates with the hardware by means of the communications subsystem or computer bus to which the hardware is connected. Device drivers are operating system-specific and hardware-dependent.
