Update: I sent the upstream bug report to Olof Johansson who added
Benson Leung to take a look. Benson sent me a set of kernel source
patches which I tested on the mainline kernel tip. The patches resolve
the issue. So now it looks like just a waiting game to get the patches
picked up.

Title:
  Touchpad of Toshiba CB30 not detected or working at all

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  Hi

  I purchased a chromebook recently and ended up with a Toshiba CB30.
  The Chromebook wasnt cool enough until hacked it and loaded Ubuntu
  onto the device

  Much to my surprise the trackpad doesnt work at all.

  The internet made some suggestions like running a script which should fix it
  https://googledrive.com/host/0B0YvUuHHn3MndlNDbXhPRlB2eFE/cros-haswell-modules.sh

  After rebooting the device. No joy!
  Following the suggestions found here:
  https://wiki.ubuntu.com/DebuggingTouchpadDetection

  dmesg > ~/dmesg
  cat /proc/bus/input/devices > ~/devices

  Which exported the output into a file see attached. I notice no
  touchpad is being detected
