how to register a device interface

NTDEV
1

I am developing a usb device driver for usb keyborad
I am confused that what GUID and class name shoud I give to it. in INF file.

when I am registering the device interface as given below

status = IoRegisterDeviceInterface(
PhysicalDeviceObject,
(LPGUID) &GUID_DEVINTERFACE_KEYBOARD,
NULL,
fdoData->InterfaceName);

it gives an error

error LNK2001: unresolved external symbol _GUID_DEVCLASS_KEYBOARD

I have inluded header files ntddkbd.h and devguid.h both…
Can you tell mewhere am I making the mistake?

You need to #define INITGUID before including either of these headers.
