>From what I can see if we enable CONFIG_USB_STORAGE_CYPRESS_ATACB then
the USB ids for the supported drives are removed from usbstorage (added
to a blacklist) and then the module starts supporting those IDs.  As
this module is not in the initramfs by default this will fail to load,
as this is your root disk your boot will fail.

The module seems to have appropriate ids on it so this looks like an
initramfs tools issue:

  alias usb:v04B4p6831d*dc*dsc*dp*ic*isc*ip* ums_cypress
  alias usb:v04B4p6830d*dc*dsc*dp*ic*isc*ip* ums_cypress


** Package changed: linux (Ubuntu) => initramfs-tools (Ubuntu)
