About the Device Property Page

The device property pages are dynamic-link libraries (DLLs) that work in conjunction with the Device Manager. They typically display property sheets for examining and modifying the settings and configuration of a device. The Device Manager provides a default property page that gives access to typical device properties. The Device Manager also gives the property page provider an opportunity to add a custom property page. The custom provider must be registered in order for the Device Manager to use it.
