2019-10-25 00:36:37 Dave Jones description 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 Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.

Note that this bug does not affect Pi 4Bs with less than 4Gb of RAM.
