[John D Marsden <1351305@xxxxxxxxxxxxxxxxxx>]

Summary:

This is fixed in kernel 3.17-rc1.

Detail:

Researching this for my daughter (Ruth Marsden) I've found this issue has been known on the kernel mailing lists for sometime.  See http://www.spinics.net/lists/linux-input/msg29123.html.
The issue relates to touchpad devices using the ALPS v7 protocol.  These devices are reported in this post to have device info as follows:
         Device ID = 0x73, 0x03, 0x0a
         Firmware ID = 0x88, 0xb*, 0x**
Which includes my daughter's Toshiba Z35 which has this Device ID and Firmware ID = 0x88, 0xb3, 0x22

A kernel patch has been in production over the last few weeks.  See http://www.spinics.net/lists/linux-input/msg32703.html and related posts.  This patch was added on 9th August and can be found in the Ubuntu kernel daily builds from then and the weekly build at http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17-rc1-utopic/ .
To install this see the "Installing upstream kernels" section of https://wiki.ubuntu.com/Kernel/MainlineBuilds .

We've tested the 3.17-rc1 kernel on my daughter's Toshiba Z35 laptop and
can confirm that both touchpad and trackpoint devices work.  They are
recognised as an AlpsPS/2 ALPS DualPoint TouchPad and the touchpad
section now appears in System Settings > Mouse & Touchpad.  In
particular "disabling while typing" is available and works.

Presumably a kernel with this patch will be released in Ubuntu in due
course.

Title:
  [Toshiba Portege Z35-AST3N01] Touchpad / Trackpoint recognised as
  generic mouse

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  On fresh install of Ubuntu 14.04 on Toshiba Portege Z30 series with
  both "Accupoint pointing device" and "Touch pad pointing device with
  multi-touch control" neither are recognised. In system settings the
  Touchpad tab is absent from System -> Preferences -> Mouse. Basic
  pointing and clicking is possible.

  Note that dmesg reports:
  ...
  [    1.197365] serio: i8042 AUX port at 0x60,0x64 irq 12
  [    1.197715] mousedev: PS/2 mouse device common for all mice
  ...
  [    1.826029] hub 2-6:1.0: 3 ports detected
  [    1.866199] psmouse serio1: alps: Unknown ALPS touchpad: E7=73 03 0a, EC=88 b3 22
  ...
  [    2.901657] input: PS/2 Generic Mouse as /devices/platform/i8042/serio1/input/input6

  Typing on the keyboard is seriously hampered by inadvertent touchpad
  contact because there is no "disable touchpad on typing" option. A
  workaround to this issue would greatly increase the usability of my
  computer.
