Title:
  USB support in intram broken for raspberry 4 after udpate

Status in initramfs-tools package in Ubuntu:
  New

Bug description:
  Hi,

  I have a Raspberry PI 4 running Ubuntu 18.04.

  Recently I apt-get upgrade'd it which resulted in new kernel and
  ramdisk.

  My initramdisk now does not recognize USB devices.

  I can see the modules are there (usb-storage uas), and I can load
  them, but no devices come up, in particular USB storage.

  I have looked at the recent commits to this package, and I wonder if
  the following commit may have had something to do, as it is recent and
  deals with device firmware and resuming devices..

  https://git.launchpad.net/ubuntu/+source/initramfs-
  tools/commit/?id=3faf13b2b7217c05a20d649b10920f828b3c83c3

  I really don't understand what is the process until USB devices are
  instantiated as /dev/disk/... so I am a bit lost in finding out
  exactly what is not working.
