Form what I understand I have a similar issue, I have a Fujitsu T4215
Tablet PC/Laptop, and the stylus wouldn't work after resuming form a
suspended state.

The issue:
- the wacom input gets removed on system suspend or resume (tested by running “xinput –list” before and after).


The solution:

NOTE: I run on Linux Mint 16 so my I cannot guarantee that the solution
will work for you.

Step 1:
Since the wacom input is setup using udev, if you run the following command “udevadm trigger –action=change” the stylus should work immediately.

Step 2:
To automate Step 1 create a text file in “/etc/pm/sleep.d”  and have its contents contain the following
------------------------------------------------------------
#!/bin/sh
# Fix to restart wacom drivers after suspend
case "${1}" in
    resume|thaw)
		udevadm trigger --action=change
		;;
esac

------------------------------------------------------------

To confirm the issue I stated above has been fixed on my laptop, which is running Linux Mint 16. I'm planing on writing a step by step guide soon (beginner level) that highlights this issue and the fix I used. If you need any help or clarification regarding my fix, will fell free to ask.

Title:
  [Fujitsu  LIFEBOOK T900] Stylus input stops working after resuming
  from suspend

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  I'm filing this bug here as per a suggestion on Ask Ubuntu:
  http://askubuntu.com/questions/377047/which-package-should-i-file-a
  -bug-against-for-pen-input

  I have a Fujitsu LifeBook T900 which accepts touchscreen input via a
  stylus which comes with the machine. It works fine until I suspend the
  laptop, such as by closing the lid, then resuming, at which point it
  immediately stops working.

  Keyboard and touchpad (mouse) still work while the bug is active. This
  is a fresh install of Ubuntu 13.10; the same machine previously ran
  12.04 LTS and did not experience the problem there.

  WORKAROUND: Restart or log out and back in.
