You are right. Though, our application is low speed only. Meaning, the hub will only be used connecting low speed devices. There may be a rare case down the line where a customer may want to hook up full speed but that will entail changing the chokes which is a simple BOM change. I need to "dial in" the EMI performance for Low speed devices only. I am wondering if there was literature for desinging low speed devices. Scouring the internet I didn't come up with much. Only for faster USB devices.
