Setting Device Object Properties in the Registry

  • Artikkel

Properties of device objects can be set in the registry as follows:

  • For WDM drivers, properties can be set for each model of a device, or for a whole device setup class. (For more information about device setup classes, see Device Setup Classes.)

  • For non-WDM drivers, properties can be set for a named device object's device setup class. The driver specifies the device setup class when it creates the device object with IoCreateDeviceSecure. For more information about how to specify a device setup class, see IoCreateDeviceSecure.

Any settings in the registry override the properties supplied when the driver created the device object.

Registry settings are specified by an INF file that is used during device installation, or they can be specified after installation by an application that calls the device installation functions.
