The important step is the claiming of the interface. The detaching of a possible kernel driver is only a step to make it more likely to succeed. Now it should be more precise. If the detachment is successful or there was no kernel driver attached or the detachment is not supported it will continue. *The last past is true on FreeBSD for example.
