 200   This function checks to see if the driver specified by This supports the device specified by
 201   ControllerHandle. Drivers will typically use the device path attached to
 202   ControllerHandle and/or the services from the bus I/O abstraction attached to
 203   ControllerHandle to determine if the driver supports ControllerHandle. This function
 204   may be called many times during platform initialization. In order to reduce boot times, the tests
 205   performed by this function must be very small, and take as little time as possible to execute. This
 206   function must not change the state of any hardware devices, and this function must be aware that the
 207   device specified by ControllerHandle may already be managed by the same driver or a
 208   different driver. This function must match its calls to AllocatePages() with FreePages(),
 209   AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
