* this identifies which controller is being initializeed. Normally, this

*
* Returned Value:

* Assumptions:
* - This function should called in the initialization sequence in order
* to initialize the USB device functionality.
* - Class drivers should be initialized prior to calling this function.
* Otherwise, there is a race condition if the device is already connected.
