You Need to change the IoCreateDevice routine in DriverEntry especially FILE_DEVICE_UNKNOWN part to say FILE_DEVICE_KEYBOARDTypes and associated changes.

PDEVICE_OBJECT deviceObject;

RtlInitUnicodeString(&deviceName, L"DeviceMyHwDriver");
RtlInitUnicodeString(&symLinkName, L"DosDevicesMyHwDriver");

status = IoCreateDevice(
    DriverObject,
    sizeof(REGISTER_EVENT),
    &deviceName,
    0, //FILE_DEVICE_UNKNOWN,
    0,
    FALSE,
    &deviceObject);

Check DDK/WDK Sample for more details. It will definitely contains samples which you can adapt..

I dont have time now to create a HID Driver sample. The Driver Video tutorial is just a basic one from which you should be able to jump start t your project. Just try it.. You will succeed..
