Update (14/08/20): It looks like this driver will be included in Linux kernel 3.17, thanks to the labors of Hans de Goede. It should no longer be necessary to use the version linked here.
Having gotten back to doing some art on computer, I decided to dust off my old Wacom Digitizer II again. It's always a bit of an adventure trying to get it to work on a new system, as some configuration system has always completely changed since the last time I hooked it up. However, this time, I discovered that while the general approach to detecting and configuring input devices had improved a lot, support for these old serial Wacom tablets had been completely removed from the xorg Wacom input driver!
Initially I was pretty irritated, as you can imagine, but after
looking at the code that had been excised, it was clear that this was
for the best. Given the new(ish) approach to handling input devices
in the Linux kernel, having all the support for the device on the X
side is now clearly the Wrong Thing. So, I set about reading as much
code as possible related to serial Wacom tablets, and writing a
Along the way, it seemed to me that this would be cleaner if protocol four (like my Digitizer II) and protocol five (newer tablets like the Intuos series) devices were supported separately. So, Intuos owners, I regret to say that the driver presented here does not support your devices, though I wouldn't mind trying to write a driver to support them.
Aside from the inevitable actual bugs to be discovered, this driver currently does not support (at least):
To use it presently, you'll need to do a few things: (instructions apply to Debian systems but should be easily adapted elsewhere)
Unpack and build the module:
$ tar xzf wacom_serial.tar.gz $ cd wacom_serial $ make all
That should produce
wacom_serial.ko if you've got things
otherwise configured correctly for building modules against your
current kernel version. Then:
$ sudo insmod ./wacom_serial.ko
Patch and build
inputattach (in the
joystick package) with the
$ apt-get source joystick $ cd joystick-1.4.1 $ patch -p1 < ~/wacom_serial/inputattach.patch $ dpkg-buildpackage $ sudo dpkg -i ../inputattach-1.4.1-1_powerpc.deb
(Adjust paths to things per your case, of course.)
70-serial-wacom.rulesfile to your local udev rules (put it in
Connect your tablet, turn it on, and run:
$ sudo inputattach --wacom_iv /dev/ttyS0
ttyS0 is the device for the serial port to which the tablet is
attached. USB serial adapters usually show up as
At this point, if everything else on your system is fairly current
xf86-input-wacom module and its configuration), your
tablet should hopefully work in X. Let me know.
So far, I've only tested it on Linux kernel 2.6.39, i386 and powerpc.
You can get the driver here: wacom serial-110702-0.tar.gz. If you
have a Wacom serial tablet, please try it out and let me know what
happens, success or failure regardless. Please also send any messages
logged (usually to
/var/log/kern.log) from the point where you
attached the device with
This driver was developed with reference to much code written by others, particularly:
gunzedrivers by Vojtech Pavlik;
wacom_w8001driver by Jaya Kumar;
xf86wacom.c(a presumably ancient version of the linuxwacom code), by Frederic Lepied and Raph Levien.
