The Adafruit TS3USB30 1 to 2 USB Switch is a nifty breakout board for the TI TS3USB30 that will let you connect one of two USB devices to a single port, handy when you have multiple chips that you may want to communicate over USB but you don't want a hub. This breakout will connect one or the other - it's designed specifically for USB so it can handle high bandwidth USB 2.0 connections of 480 Mbps.
