  01 June 2000

  This is the Wacom Graphire USB Mini-HOWTO. This document describes how
  to setup a Wacom Graphire USB tablet for use with Linux (console and
  X), starting with the kernel configuration to the application level.
  But information should be accurate for the Intuos USB tablet.

  2.  Introduction

  This document is a guide to getting your Wacom Graphire USB tablet to
  working with Linux. Beware, this is a quite difficult task, but this
  guide will guide you, step-by-step, through the process.

  This work is mainly derived from the Wacom Tablet HOWTO by Stephan
  Runkel, but brings some precisions about all the USB configuration
  that is absent from the original document. If you want more precision
  about general Wacom Tablets, please read Stephan Runkel's HOWTO.

  I have written this document because I've had many difficulties in
  setting up my brand new Graphire tablet with Linux, but now it works
  quite well on my Toshiba 4030CDT Laptop.

  2.1.  New versions of this document

  New version of this document will be made available at the following

  2.3.  Acknowledgements

  I wish to thank everyone that work on the USB part of the kernel, and
  special thanks go to Vojtech Pavlik for his work on the wacom module.

  Of course, I thank Stephan Runkel for his great Wacom Tablet HOWTO
  that helped me much in the configuration process.

  Special thanks also go to Frederic Lepied for his work on the
  xf86Wacom module.

  2.4.  Disclaimer

  The information in this document is correct to the best of my
  knowledge, but there's a always a chance I've made some mistakes, so
  don't follow everything too blindly, especially if it seems wrong.
  Nothing here should have a detrimental effect on your computer, but
  just in case I take no responsibility for any damages incurred from
  the use of the information contained herein.This document is not a
  kernel howto, so I'll take the assumption that you know how to
  download/install a new kernel, and how to configure/compile it.

  3.  Requirements



  3.1.  Hardware

  The main part is, of course, a computer with at least one USB port and
  a Wacom Graphire USB tablet.

  3.2.  Kernel

  I've used the latest development kernel for my installation :
  linux-2.3.99-pre6.  It's quite stable and has all the necessary
  features. You can also find some downports, which are patches for old
  2.2.x kernels. You can find all the infos on the backport at
  http://www.suse.cz/development/usb-backport

  3.3.  Console Software

  For the Linux console, the only program you need is gpm, available at
  ftp://ftp.prosa.it/pub/gpm

  3.4.  XWindow

  For having all the abilities of your tablet, you'll need to use
  XInput.  More specifically you'll need the xf86Wacom.so module (that
  is shipped with the most recent versions of XFRee86 starting from
  3.3.5). Alternately, you may need the xf86WacomUSB.so, which is a
  work-in-progress of adapting the original xf86Wacom.so to use the USB.
  I'll speak of it later in this document.

  3.5.  Others

  The applications supporting XInput are :


  1. The Gimp - a powerful image manipulation program in the style of
     Photoshop.  The 1.1.x instable development version includes XInput
     support as a standard feature. You can obtain Gimp from
     http://www.gimp.org

  2. gsumi - a simple B/W drawing program that supports drawing /
     erasing with pressure and tilt sensitivity. Get it from the gsumi
     web page: http://www.gtk.org/~otaylor/gsumi/

  3. xink (By Ralph Levien) - another rudimentary drawing program for X.
     xink is available from:
     ftp://kiwi.cs.berkeley.edu/pub/raph/xink.tar.gz

  4. RasMol - a molecular visualization program that supports a hardware
     dial box using XInput. look at
     http://www.umass.edu/microbio/rasmol/distrib/rasman.htm .

  5. xinput (by Frederic Lepied) - a very useful utility for configuring
     and testing XInput devices. xinput is available from:
     ftp://ftp.x.org/contrib/utilities/xinput-1.2.tar.gz

  4.  Kernel and hard stuff

  4.1.  Kernel configuration

  Like I said earlier, the options I'll give come from the 2.3.99pre6
  kernel.  If everything is not exactly the same, I think that taking a
  good guess should help ;)

  ** Reminder : [] stands for Yes/No options, and <> stands for
  Yes/No/Module **

  First of all, you have to enable the experimental code :

  Code Maturity level options --->

  [*] Prompt for development and/or incomplete code/drivers

  If you don't, you won't have access to some of the drivers.

  Then, move on to the USB section.

  USB support --->

  <*> Support for USB

  [*] USB verbose debug messages

  --- Miscellaneous USB options

  [*] Preliminary USB device filesystem

  With this option, you'll activate the new features of the /dev/usb/*
  (which, of course, you'll have to create : to be seen later)

  --- USB controllers

  <*> UHCI (Intel PIIX4, VIA, ...) support

  < > OHCI (Compaq, iMacs, OPTi, SiS, ALi, ...) support

  You must choose one of these, and only one. So, if one doesn't work,
  then choose the other. Chances are that, if you use an x86 system,
  you'll take the UHCI driver.

  --- USB Devices

  < > USB Printer support

  < > USB Scanner support

  < > USB Audio support

  < > USB Modem (CDC ACM) support

  If you have one of these, feel free to activate the options

  <M> USB Serial Converter support

  This options must be activated for the Wacom tablet to work.

  [*] USB Generic Serial Driver

  [ ] USB Handspring Visor Driver

  [ ] USB ConnectTech WhiteHEAT Serial Driver (EXPERIMENTAL)

  [ ] USB FTDI Single Port Serial Driver (EXPERIMENTAL)

  [ ] USB Keyspan PDA Single Port Serial Driver (EXPERIMENTAL)

  [ ] USB ZyXEL omni.net LCD Plus Driver (EXPERIMENTAL)

  [*] USB Serial Converter verbose debug

  If you want to have all the messages (which can be very helpful in the
  beginning). When satisfied with the functionning, you can deactivate
  it.


  < > USB Kodak DC-2xx Camera support

  < > USB Mustek MDC800 Digital Camera support (EXPERIMENTAL)

  < > USB Mass Storage support (EXPERIMENTAL)

  < > USS720 parport driver

  < > DABUSB driver

  < > PLUSB Prolific USB-Network driver (EXPERIMENTAL)

  < > USB ADMtek Pegasus-based device support (EXPERIMENTAL)

  < > USB Diamond Rio500 support (EXPERIMENTAL)

  --- USB HID

  The HID is kinda the interface between you and your devices, so you
  MUST activate it.

  <M> USB Human Interface Device (HID) support

  < > USB HIDBP Keyboard support

  < > USB HIDBP Mouse support

  <M> Wacom Intuos/Graphire tablet support

  There we go, the Wacom support should be activated (unless you read
  this just for fun ;) )

  < > Logitech WingMan Force joystick support

  < > Keyboard support

  <M> Mouse support

  To be activated to use the Wacom Intuos/Graphire mouse

  (1024) Horizontal screen resolution

  (768) Vertical screen resolution

  <M > Joystick support

  <M> Event interface support

  4.2.  Kernel compilation

  Now the easy stuff :

  When you exit the configuration do as they say

  make dep bzImage modules modules_install

  Type it just like this and the computer will run all the steps one
  after the other.

  Then copy the file bzImage to /boot, copy the System.map to /boot,
  edit your lilo.conf to point to your new kernel and type /sbin/lilo at
  the prompt.

  ** Of course all of this (kernel config, kernel compilation and lilo
  tweaking must be done as root) **

  4.3.  Before rebooting

  4.3.1.  FStab

  If you want to avoid error messages at the next reboot, you'll have to
  do the following :

  Edit the file /etc/fstab and add the following lines

  none          /proc/bus/usb          usbdevfs          defaults
  0          0

  This one is to activate the usb device filesystem

  none          /var/shm                    shm
  defaults          0          0

  This one is because of a change in the shared memory stuff in the
  kernel.

  4.3.2.  USB related devices

  Next, if you want to be able to use the USB :

  mkdir /dev/input

  mknod /dev/input/mouse0 c 13 32

  This will activate the mouse support

  mknod /dev/input/event0 c 13 64

  mknod /dev/input/event1 c 13 65

  mknod /dev/input/event2 c 13 66

  mknod /dev/input/event3 c 13 67

  These will activate the stylus : moves, pressure, button and eraser.

  4.3.3.  Modules configuration

  Edit the file /etc/modules.conf and add the following line :

  alias char-major-13 usbcore

  4.3.4.  What I did next

  Next I added in the /etc/rc.d/boot.local file (remember, I use a SuSE
  distribution, but you should fine an equivalent for RedHat in
  /etc/rc.d/init.d/boot.local or /etc/rc.d/init.d/rc.local)

  /sbin/modprobe wacom

  /sbin/modprobe mousedev

  /sbin/modprobe evdev

  Just to be sure the modules will load at boot time.

  4.3.5.  Last but not least

  Reboot ;)

  Check your boot messages (dmesg | less), and see if there are no
  errors related to USB. It may be because you've chosen UHCI and your
  system is an OHCI one.

  On my system, the following messages are shown :

  .....

  .....

  Configuration:

  .....

  When the kernel says "This device is not recognized by any installed
  USB driver", it's because, at boot time, the wacom module is not yet
  loaded. But as you can see, the whole USB bus and interfaces are
  recognized. So if your system doesn't work and doesn't have such
  messages, try to check if you haven't forgotten an USB option
  (something I indicated to be put in the kernel and that you put as a
  module : if it's the case, in the /etc/rc.d/init.d/boot.local, put the
  necessary modprobe BEFORE the 3 lines I indicated, for example
  /sbin/modprobe usb-uhci).

  When the wacom module loads, here are the messages :

  .....

  .....

  usb.c: registered new driver wacom

  input0: Wacom Graphire on usb2

  usb.c: wacom driver claimed interface c3fcd620

  mouse0: PS/2 mouse device for input0

  mice: PS/2 mouse device common for all mice

  event0: Event device for input0

  .....

  .....

  Retry and check everything until you get all these messages (or
  corresponding ones).

  5.  The Linux console

  Now that you have your USB activated, it's just about time to try it
  all with gpm :

  If gpm is activated at boot time, you'll have to kill it : gpm -k

  Then try your Wacom tablet : gpm -tIMPS/2 -m /dev/input/mouse0

  Move your stylus, or your mouse, and TADA ... the cursor moves on the
  screen.

  6.  XWindow

  6.1.  Having 2 mouses on the same system

  Have you ever dreamed of having 2 mouses on your system ? If the
  answer is yes, do the following.

  Edit the file /etc/XF86Config

  The modules section should look like this

  Section "Module"

  Load "xf86Wacom.so"

  EndSection

  Then check the XInput section :

  Section "XInput"

  SubSection "Mouse"

  DeviceName "WacomTablet" --> or whatever you like

  Protocol "IMPS/2" --> I didn't manage to have imwheel recognize the
  wheel, but if you do, drop me an email

  Port "/dev/input/mouse0"

  Buttons 5

  ZAxisMapping 4 5

  AlwaysCore --> means that the Wacom mouse is always considered as the
  core pointer, ie if you move your normal mouse or the Wacom mouse (or
  stylus), it'll be just the same.

  EndSubSection


  EndSection

  And there you are, the Wacom mouse (or stylus) is now considered as a
  second mouse, but your normal one still works.

  6.2.  Now on to the real stuff

  Back to the XInput section, after the parameters for the mouse, here
  is the real Wacom stuff :

  SubSection "WacomStylus"

  Port "/dev/input/event0" --> the USB event device

  DeviceName "WacomStylus" --> or whatever you want to call it

  Mode Absolute --> ie the tablet surface is equivalent to the screen
  surface

  #Suppress 6

  DebugLevel 10 --> once everything works, set it to 0

  #TiltMode

  #HistorySize 200

  #AlwaysCore

  #KeepShape

  #TopX 20412 --> the 4 lines are used to fine-tune the coordinate to
  fit with the screen

  #TopY 14730

  #BottomX 0

  #BottomY 0

  EndSubSection

  SubSection "WacomEraser"

  DeviceName "/dev/input/event0"

  DeviceName "WacomEraser"

  Mode Absolute

  EndSubSection

  SubSection "WacomCursor"

  Port "/dev/input/event0"

  DeviceName "GraphireMouse"

  Mode Absolute

  EndSubSection

  6.3.  The new module

  The xf86Wacom.so is not specifically written for the USB tablets, and
  it's even not working correctly with these tablets. A new driver has
  been written by Matsumura Namihiko <po-jp@geocities.co.jp> has written
  one named xf86WacomUSB (available as source code at the same location
  than this Mini-HOWTO). However, to be able to compile it, you'll need
  the kernel source code and the source tree for XFree86 (I compiled it
  with success against XFree86 3.3.5, but it should compile with 3.3.6).

  This driver doesn't handle all the possibilities of the tablet, and
  crashes if you pass it the AlwaysCore parameter.

  To correct this, I'll keep in touch with Frederic Lepied for a
  modification of the original module to have it handle all of the
  possibilities of the tablet.

  **NEWS** At Frederic Lepied's site, you'll find a link to a new USB
  driver that works perfectly well, but exclusively with the possibility
  to have your tablet working as a mouse : ie either you use your tablet
  in The Gimp to draw, or you use it as an XFree mouse, but not both
  together. I'll investigate further, and update this document
  accordingly.
