TUSB7340 configuration

Is any configuration required of the 7340 to enumerate the usb bus or is this a built in state machine to the device. I am writing a custom driver and this information is not apparent in the manual

    Hi Roy, the 7340 is xHCI spec compliant and operates the same as all other standard USB3.0 controllers.  Your driver should follow that specification which is availabe on USB.org.  After you have configured the controller registers appropriately and a device is attached, the controller will notify the driver which is responsible for handling all data transfers required for enumeration.  You can reference the open source Linux driver code to get a better idea of what's involved.
