USB hub device

Hi, I have a custom hub device which has control endpoints. On sending certain control messages the device in the downstream is enabled. Now, my approach as i think : Register a driver as hub class driver with appropriate match flags. In my probe i send vendor specific commands on control endpoint to the hub which enables the device. Here, my question is : Will the device enumeration end up in my driver or will the kernel hub driver still do the enumeration ? If the enumeration ends up in my driver, how can i let the kernel hub driver do that ? Thanks, learner
