+ This function checks to see if the driver specified by This supports the device specified by\r
+ ControllerHandle. Drivers will typically use the device path attached to\r
+ ControllerHandle and/or the services from the bus I/O abstraction attached to\r
+ ControllerHandle to determine if the driver supports ControllerHandle. This function\r
+ may be called many times during platform initialization. In order to reduce boot times, the tests\r

+ function must not change the state of any hardware devices, and this function must be aware that the\r
+ device specified by ControllerHandle may already be managed by the same driver or a\r
+ different driver. This function must match its calls to AllocatePages() with FreePages(),\r
+ AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().\r
+ Since ControllerHandle may have been previously started by the same driver, if a protocol is\r
+ already in the opened state, then it must not be closed with CloseProtocol(). This is required\r
