I'm designing a board which has a single USB 2.0 PHY, currently connected with the high speed pairs to a USB 3.0 port. I have another part on the board that needs a USB 2.0 connection. Can I just use a 2-port USB2.0 hub IC to split the USB2 interface to the device and the USB3 socket? Will it cause issues for the USB3 port if the USB2 part of it is going through a hub? Or do I need to use a USB3.0 hub and only use the USB2 part of it for the second device? Footprint is an issue and I'd rather use the smaller parts if I can do it.
