I just wanted to report that USB is working for me with the 5.3.0-1014-raspi2 aarch64 kernel, but neither the keyboard not the mouse works at boot time when I have my mouse (a Microsoft Basic Optical Mouse v2.0) plugged in via my Apple USB keyboard's built-in USB hub.
I must disconnect the mouse from the keyboard and plug it straight into an open USB port on the Pi. Afterwards, I can then plug it back into the keyboard, and the keyboard and mouse both work fine until reboot.
That was confusing me into thinking that I was seeing this issue, when it's probably a little different. I don't have another hub to test to see if the same happens with all USB hubs.
