101 | \r | |
102 | This function checks to see if the driver specified by This supports the device specified by\r | |
103 | ControllerHandle. Drivers will typically use the device path attached to\r | |
104 | ControllerHandle and/or the services from the bus I/O abstraction attached to\r | |
105 | ControllerHandle to determine if the driver supports ControllerHandle. This function\r | |

107 | performed by this function must be very small, and take as little time as possible to execute. This\r | |
