  USB fails on RPi 4 20.04 daily build image focal-preinstalled-server-
  arm64+raspi.img

Bug description:
  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:

  ~# lsusb -v -t
  /:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 5000M

  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.
