Device drivers are needed for any device that is connected to your computer, but how are they developed and made? To write the programming for device drivers, you must have advanced knowledge of how the software and hardware of a specific platform works and functions. If the device drivers are not written exactly right, they can cause damage to your computer, device, or operating system.

If you are using software at the user level and the program is stopped, it usually only affects that one specific program. With device drivers, however, if the program just stops, the whole operating system may crash and be damaged beyond repair. This may occur because the device drivers are programmed wrong.

Device drivers are normally created and written by people who have extensive knowledge and training of software and hardware, called software engineers. These software engineers normally work for the companies who develop the hardware, and this is because they are in a better position to understand the design and function of the hardware, including any secret or patented information.

The device drivers are created by the hardware manufacturer because they are needed to run the hardware, so the manufacturer has a vested interest in making sure the device drivers are written and designed correctly. The logical device drivers used to be developed by the vendor of the operating system, and the vendor of the device used to develop the physical device driver, but that has changed.

Many device drivers in recent years have been written by non-vendors, especially in the area of no cost operating systems. Device drivers can not be written without all the relevant information and specifications on how the device communicates, and having all this information will allow software engineers to design the correct device drivers which work effectively.

Device drivers can be written without having access to the manufacturer’s information, but this method can be very complex and difficult. Reverse engineering is used by software engineers to enable them to learn the needed information about the device. This will let the software engineers develop the correct device drivers, without errors that can cause your system to crash and may cause damage.

Using reverse engineering with hardware is not as easy to do as it is with software though, so every effort should be made to get the information from the manufacturer if possible before the device drivers are written. Microsoft has made big advances in reducing the effects of badly created device drivers, because of the creation of Windows Driver Foundation, which is a newly created driver development framework.

This framework allows the User Mode Driver Framework, which encourages the development of device drivers that do not cause system instability, and have no chance of causing damage to your system. The Kernel Mode Driver Framework is also included in the Windows Driver Foundation, which will allow the development of kernel mode device drivers, but with certain safety features and standards implemented to help reduce system instability.
