Official Hardware Classic Zero

I can read two usb devices(keyboard and mouse) just fine but one at a time. What I want is to use or read both usb devices at the same time. Is this possible? How?

If you want to read both devices, you'll have to connect your 2 devices behind a hub, AND program the USB host accordingly (see Jan Axelson book).
