Remarks
Windows sets the value of DEVPKEY_Device_Capabilities to the capability value that the device driver returns in response to an IRP_MN_QUERY_CAPABILITIES request for device capability information. The value of DEVPKEY_Device_Capabilities is a bitwise OR of the CM_DEVCAP_Xxx capability flags that are defined in Cfgmgr32.h. The device capabilities that these flags represent correspond to a subset of the members of the DEVICE_CAPABILITIES structure.
You can call CM_Get_DevNode_Property or SetupDiGetDeviceProperty to retrieve the value of DEVPKEY_Device_Capabilities.
Windows Server 2003, Windows XP, and Windows 2000 support this property, but do not support the DEVPKEY_Device_Capabilities property key. Instead, you can use the corresponding SPDRP_CAPABILITIES identifier to access the value of the property on these earlier versions of Windows. For information about how to access this property value on these earlier versions of Windows, see Accessing Device Instance SPDRP_Xxx Properties.
