I found this routine, /** * usb_register_root_hub - called by HCD to register its root hub * @usb_dev: the usb root hub device to be registered. * @parent_dev: the parent device of this root hub. * * The USB host controller calls this function to register the root hub * properly with the USB subsystem. It sets up the device properly in * the device tree and stores the root_hub pointer in the bus structure, * then calls usb_new_device() to register the usb device. It also * assigns the root hub's USB address (always 1). */ int usb_register_root_hub (struct usb_device *usb_dev, struct device *parent_dev)
But who is the parent device of a root hub?The host controller?
