Example #2

// **if passed an existing DirectInputDevice which matches gGuid
//		unacquires it, and sets its cooperative level (reinitialize)
// **if the existing device does not match the passed gGuid, the existing device is released
// **if no device was passed or gGuid did not match
//		searches for the controller matching gGuid in connected and available devices
//		creates a DirectInputDevice
//		sets its data format
//		sets its cooperative level
//		for joysticks, calls EnumSetObjectsAxis for each axis
// GetInputDevice always leaves the returned device in an UNACQUIRED state.
