As asked above do other USB devices still work?

Did you run rpi-uboot-update?
Oops, sorry; yes, other USB devices work, e.g. USB 3.0 disk, plugged
into USB 3 socket. The XMOS USB audio device is in a USB 2 socket.
I did not run rpi-uboot-update, because it was not an upgrade from an
older release ...
... and yes, the rpi-uboot-update fixes it! Hoorah. Many thanks, Peter. :)
Why did the rpi-uboot-update make a USB device reappear? I thought dnf
updates did all that sort of thing nowadays.
Is there some documentation somwhere for rpi-uboot-update, please?
