Кошмаp.
    RtlInitUnicodeString(&ntMouseUnicodeString,L"\\Device\\PointerClass0");
    RtlInitUnicodeString(&ntUnicodeString,L"\\Device\\KeyboardClass0");
Освобождать не надо.

Вот этого не нужно.
В usermode:
  if(!DefineDosDevice(DDD_RAW_TARGET_PATH,"Kbddmr","\\Device\\KeyboardClass0"))
  {
    return 0;
  }
  hDevice = CreateFile("\\\\.\\Kbddmr", GENERIC_WRITE,
                       FILE_SHARE_WRITE|FILE_SHARE_READ,NULL,
                       OPEN_EXISTING,0,NULL);
  if (hDevice==INVALID_HANDLE_VALUE){}



 VP> NTSTATUS ViPReadComplete(
 VP>     IN PDEVICE_OBJECT DeviceObject,
 VP>     IN PIRP Irp,
 VP>     IN PVOID Context)
 VP> {
 VP>     if( Irp->PendingReturned ) {
 VP>         IoMarkIrpPending( Irp );}
 VP>     if ( iKeyboardBlocked ) {
 VP>         Irp->IoStatus.Status = STATUS_UNSUCCESSFUL;}
Irp->IoStatus.Status = STATUS_CANCELLED;
 VP>     return Irp->IoStatus.Status;}
