Comment # 19 on bug 1180336 from Ang

Just tested in snapshot 20210203 with the kernel-default 5.10.12 on my
Raspberry Pi 4 4GB HW Revision 1.1. I am using the latest eeprom in the
Raspberry Pi 4 stable branch. When booting the installation DVD for Tumbleweed
Aarch64 20210203, one loses all USB devices after the Grub2 menu where you can
select Installation..., Boot from hard disk, etc. It will progress to the
graphical license screen, but one cannot select anything or input anything
using USB input devices in order to proceed with installation.

I also tested the prebuilt snapshot 20210203 images for Raspberry Pi 4, and it
will not be able to proceed to mounting and setting up filesystems (will time
out) if installed on a USB key. If booted from an SD card, it will boot, but
one has no USB after the Grub2 menu.
