471 | This function checks to see if the driver specified by This supports the device specified by \r | |

473 | ControllerHandle and/or the services from the bus I/O abstraction attached to \r | |
474 | ControllerHandle to determine if the driver supports ControllerHandle. This function \r | |
475 | may be called many times during platform initialization. In order to reduce boot times, the tests \r | |
476 | performed by this function must be very small, and take as little time as possible to execute. This \r | |
477 | function must not change the state of any hardware devices, and this function must be aware that the \r | |
478 | device specified by ControllerHandle may already be managed by the same driver or a \r | |
479 | different driver. This function must match its calls to AllocatePages() with FreePages(), \r | |
480 | AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol(). \r | |
481 | Because ControllerHandle may have been previously started by the same driver, if a protocol is \r | |
482 | already in the opened state, then it must not be closed with CloseProtocol(). This is required \r | |
