Exclusively opens a connection to the in-kernel device. As long as the in-kernel device object is open, no other drivers will be able to open a connection to the device. When open the device on the bus may disappear, but the in-kernel object representing it will stay instantiated and can begin communicating with the device again if it ever reappears.
