For the last few days the daily 20.04 pre-installed server image fails
to boot correctly on a Raspberry Pi4 with 4G of memory. The image is
called: focal-preinstalled-server-arm64+raspi.img.
The image available over the last weekend (18/19 April) failed to boot,
and today's image boots but USB devices do not work (on both USB2 and
USB3 ports).
Please refer to bug #1872897 comment #4 which says that USB issues
should have been fixed, but I'm not sure that they have.
Here the output from lsusb -v -t on today's image:
~# lsusb -v -t
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 5000M
ID 1d6b:0003 Linux Foundation 3.0 root hub
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/1p, 480M
ID 1d6b:0002 Linux Foundation 2.0 root hub
Here is the output from the latest 20.04 beta release (ubuntu-20.04
-beta-preinstalled-server-arm64+raspi.img) after it has been upgraded
(with apt full-upgrade) to today's packages:

Early on in the boot process the following appears in syslog:
usb usb1-port1: couldn't allocate usb_device
Maybe the arm64 kernel's USB issue has crept back in? Thanks.
