Thank you for taking the time to report this bug and helping to make
Ubuntu better.

Do you still have the problem or did you upgrade to Ubuntu 20.04 or
22.04?

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

Status in initramfs-tools package in Ubuntu:
  Incomplete

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.
