There exist some common interface formats for interfacing with a USB device. I think it would be valuabel for any core handling the low levels of a USB interface to talk to the next level up using a common interface format. You may wish to look up what interfaces various USB peripherals use and see if you can match those, for example.

If your planning to develop RTL for USB 3.0 and USB3.1 give some inputs i can join with you.
i have working experience in the USB protocol layer and link layer.
