How to Use the Device Access API

This topic contains tasks and design considerations for using the Device Access API.

Steps

Topic	Description
Design Considerations for Custom Devices	This topic describes design considerations that can help you determine whether your device needs a custom driver.
Implement the Device Access Object	This topic explains how to instantiate the device access object and use it to access a device.
Declaring the Device Capability	This topic explains how to declare the device capability GUID.
Register the device interface as restricted to privileged apps	This topic shows how to add the Restricted property that indicates that only privileged apps can access a device interface class.
Create a Windows Runtime Extension	You can create a Windows Runtime component to wrap the component that accesses your driver. You can then write a Windows Store device app for your device in C# or JavaScript.

The Custom Driver Access Sample demonstrates how to use the Device Access API to access a custom driver from a Windows Store device app.
The Windows Store device app design guide for specialized devices provides design guidance on what types of specialized devices require custom driver access via the Device Access API.
