event again. This process continues until the co-installer does not

signal anymore; finally, the configuration tool waiting for the event

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.
