Device Manager (Windows CE 5.0)

Send Feedback

The Device Manager is loaded by the kernel, it runs continuously, and it manages loaded device drivers and their interfaces. When the Device Manager loads, it also loads the I/O Resource Manager to read a list of available resources from the registry.

The Device Manager tracks interfaces advertised by drivers and supports searches for drivers based on a globally unique identifier (GUID). The IClass interface can associate an interface GUID with the driver's legacy name, its $device name, or its $bus name. For example, COM1:, $device\com1, or $bus\pci_0_3_0.
