Remarks
The value of DEVPKEY_Device_Characteristics is a bitwise OR of the FILE_Xxx file characteristic flags that are defined in Wdm.h and Ntddk.h. For more information about the device characteristic flags, see the DeviceCharacteristics parameter of IoCreateDevice and Specifying Device Characteristics.
You can set the value of DEVPKEY_Device_Characteristics by using an INF AddReg directive that is included in the INF DDInstall.HW section that installs a device.
You can retrieve the value of DEVPKEY_Device_Characteristics by calling SetupDiGetDeviceProperty.
Windows Server 2003, Windows XP, and Windows 2000 support this property, but do not support the DEVPKEY_Device_Characteristics property key. Instead, you can use the corresponding SPDRP_CHARACTERISTICS 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.
