[Bug 1946475] [NEW] USB support in intram broken for raspberry 4 after udpate

[Rafael]

Public bug reported:

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.

** Affects: initramfs-tools (Ubuntu)
     Importance: Undecided
         Status: New
