Public bug reported:
Ubuntu 19.10 arm64 on a Raspberry Pi 4 does not recognize a keyboard
which works successfully on the same Raspberry Pi 4 with Ubuntu 19.10
armhf. Both USB hubs (2 and 3) were tested, without the OS seeing the
keyboard on either. Booting the arm64 image on a Raspberry Pi 3, the
keyboard worked successfully.
Output of lsusb under arm64 on a Pi 3:
ubuntu@ubuntu:~$ lsusb
Bus 001 Device 007: ID 413c:2106 Dell Computer Corp. Dell QuietKey Keyboard

Output of lsusb under armhf on a Pi 4 (same keyboard attached):

Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Output of lsusb under arm64 on the same Pi 4 (same keyboard attached):
ubuntu@ubuntu:~$ lsusb
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
The fact even the VIA Labs hub doesn't show up (which is built in)
suggests the kernel is (for some reason) unable to enumerate anything
against the USB hubs.
