TS3USB30 USB mux tester is a go! ππ¬π»
The Adafruit TS3USB30 1 to 2 USB Switch is a nifty breakout board for the TI TS3USB30 (https://www.digikey.com/en/products/detail/texas-instruments/TS3USB30ERSWR/2092506) 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. Our new breakout will connect one or the other. We designed for USB to handle high bandwidth USB 2.0 connections of 480 Mbps. But before we put it into stock, we gotta test it! This tester has two different USB peripherals connected: a CP2102 on a Metro Mini and an FT232RL in a console cable. We're using the Metro RP2040's bit-banging USB host stack (https://learn.adafruit.com/adafruit-feather-rp2040-with-usb-type-a-host) to test enumeration: when the RP2040 detects two different PIDs based on the switching pin, we know the board is good!
