No; the subsystem rw-semaphore is used by the driver model core when driver-model struct device's are added or removed. It is not held while usb_disconnect recurses through the tree of struct usb_device's, which is when usbdev->children[] gets used. It's only held during the time that an individual device or interface is unregistered.
