HOW TO Set Up a Wacom Serial Tablet in Ubuntu

[bogamol]

Ok, the new thread is here.

[Cognuss]

Hello,
I am an archlinux user with a newly set up system running xfce, with kernel 3.8.4-1.
I am trying to get a wacom artz2(UD-1212-R) tablet to work using a pl2303 usb-serial converter.

1 I have downloaded wacom_serial-120327-1.tar.bz2.

2 I have modified wacom_serial.c(changed #define SERIO_WACOM_IV 0x3d to #define SERIO_WACOM_IV 0x3e)
and serio-ids.h(changed # define SERIO_WACOM_IV 0x3d to # define SERIO_WACOM_IV 0x3e)

3 I then did these commands to make and install it:
make all
sudo cp inputattach /usr/bin
sudo cp wacom_serial.ko /lib/modules/`uname -r`/kernel/drivers/input/tablet
sudo depmod -a

4 I then started inputattach with the command:
sudo inputattach --wacom_iv /dev/ttyUSB0

dmesg shows the error:
wacom_serial: probe of serio5 failed with error -5
serio: Serial port ttyUSB0
input (null): Timed out waiting for tablet to respond with model and version.
This is repeated over and over again.
If I touch the pen to the tablet dmesg shows:
input (null): got a garbled response of length #.
input (null): Timed out waiting for tablet to respond with configuration string. Continuing anyway.
input (null): Timed out waiting for tablet to respond with coordinates string. Continuing anyway.
input: Wacom protocol 4 serial tablet as /devices/pci0000:00/0000:00:14.0/usb1/1-2/1-2:1.0/ttyUSB0/tty/ttyUSB0/serio15/input/input14

Xorg.0.log shows this:
[ 175.135] (II) config/udev: Adding input device Wacom protocol 4 serial tablet (/dev/input/event14)

Any help would be appreciated.

Hi Cognuss,

Welcome to Ubuntu forums!


Not sure what is going on. You're the first to report trying the 3.8 kernel as far as I am aware. What is the X Server?

Xorg -version

I'm assuming:

[ 175.182] (EE) Wacom protocol 4 serial tablet stylus: unable to ioctl xmax value.
[ 175.186] (EE) PreInit returned 8 for "Wacom protocol 4 serial tablet stylus"
[ 175.186] (II) UnloadModule: "wacom"

is due the dmesg error.

I'm trying to remember if the pl2303 usb-serial converter has the ioctl patch for xf86-input-wacom. I think it did last time I looked. Which was a long time ago admittedly. I have the impression most the the converter's kernel drivers had been updated. Discussed a bit in:

"Configuring A Wacom Tablet In Lucid Lynx" thread: http://ubuntuforums.org/showthread.php?t=1462026&page=3 - setting up a serial Wacom ArtzII tablet using a Keyspan serial->USB adapter, posts #24 to #34 with HOW TO at #34. Kernel patch for the Keyspan serial-to-USB driver, adds a dummy TIOCGSERIAL ioctl, on post #30.

Although it seems to me the ioctl grab was dropped in xf86-input-wacom a few releases ago and you now have to request it with a .conf option. What version do you have?

xsetwacom -V

[Cognuss]

The X Server is version: 1.14.0 and xsetwacom -V returns: 0.20.0.
Also in case I wasn't clear nothing recognizes the tablet unless,
the pen is being pressed onto the tablet like your drawing.

I forgot to tell you that I added the 70-serial-wacom.rules to /etc/udev/rules.d and this is what it contains:
ACTION=="add|change", SUBSYSTEM=="tty|pnp", ENV{NAME}="Wacom protocol IV serial tablet",
SYMLINK+="input/wacom", ENV{ID_INPUT}="1", ENV{ID_INPUT_TABLET}="1"

Incase you need it, here is what 50-wacom.conf, for xorg, contains:

Section "InputClass"
Identifier "Wacom class"
MatchProduct "Wacom|WACOM|Hanwang|PTK-540WL"
MatchDevicePath "/dev/input/event*"
Driver "wacom"
EndSection

Section "InputClass"
Identifier "Wacom serial class"
MatchProduct "Serial Wacom Tablet"
Driver "wacom"
EndSection

Section "InputClass"
Identifier "Wacom serial class identifiers"
MatchProduct "WACf|FUJ02e5|FUJ02e7|FUJ02e9"
Driver "wacom"
EndSection

# Waltop tablets
Section "InputClass"
Identifier "Waltop class"
MatchProduct "WALTOP"
MatchIsTablet "on"
MatchDevicePath "/dev/input/event*"
Driver "wacom"
EndSection

# N-Trig Duosense Electromagnetic Digitizer
Section "InputClass"
Identifier "Wacom N-Trig class"
MatchProduct "HID 1b96:0001|N-Trig Pen"
MatchDevicePath "/dev/input/event*"
Driver "wacom"
Option "Button2" "3"
EndSection

I do not have an xorg.conf file.
I don't know anything about ioctl.
Thank you for your help.

You shouldn't need the udev rule. Go ahead and comment it out and see if it makes a difference.

You appear to be the first person reporting trying the wacom_serial.ko on basically the latest kernel, X Server, and xf86-input-wacom. Perhaps that's where the problem is. If so we'd need tokenrove to take a look.

When the serio driver is querying the tablet you are getting:

dmesg shows the error:
wacom_serial: probe of serio5 failed with error -5
serio: Serial port ttyUSB0
input (null): Timed out waiting for tablet to respond with model and version.
This is repeated over and over again.
If I touch the pen to the tablet dmesg shows:
input (null): got a garbled response of length #.
input (null): Timed out waiting for tablet to respond with configuration string. Continuing anyway.
input (null): Timed out waiting for tablet to respond with coordinates string. Continuing anyway.
input: Wacom protocol 4 serial tablet as /devices/pci0000:00/0000:00:14.0/usb1/1-2/1-2:1.0/ttyUSB0/tty/ttyUSB0/serio15/input/input14

So either the tablet is not responding in the expected time windows or it is garbling the protocol: http://sourceforge.net/apps/mediawik...al_Protocol_IV

You need to establish communication with the tablet. Does the tablet work in another release or OS? That would rule out bad hardware.

It is possible setting it up through xorg.conf might help initialize it.

[Cognuss]

Commenting out the udev rule doesn't appear to do anything. So I'll leave it commented out.
I should clarify that I don't always get the configuration and coordinates string errors,
sometimes it is just one or the other or none.
No it isn't a hardware problem, it works on windows xp.
What should I put in xorg.conf?
Thanks again.
Cognuss

[Favux]

Good, hardware ruled out.

Be sure you are comfortable editing xorg.conf with nano from the command line using the Recovery Mode option in case you break X.

The second part of the HOW TO post "Old serial tablet driver - for Lucid & Maverick" has a sample xorg.conf. Start with just the stylus section. If that doesn't break X with a restart then add the ServerLayout section. But you can comment out the eraser and pad lines for now since you haven't added those sections yet. Of course instead of:

    Option        "Device"         "/dev/ttyS0"

you would use:

    Option        "Device"         "/dev/ttyUSB0"

[Cognuss]

Okay I added:

Section "ServerLayout"
Identifier "X.org Configured"
InputDevice "stylus"
EndSection

and:

Section "InputDevice"
Driver "wacom"
Identifier "stylus"
Option "Device" "/dev/ttyUSB0"
Option "Type" "stylus"
Option "ForceDevice" "Serial"
EndSection

to the xorg.conf file created by nvidia.

Then I started the computer with tablet plugged in, without the pen drawing on the tablet.
xorg log shows this about the tablet:

I then opened the terminal and typed sudo inputattach --wacom_iv /dev/ttyUSB0
dmesg shows this:
[ 182.536439] serio: Serial port ttyUSB0
and xorg log doesn't show anything else.

I started the computer with the tablet plugged in and with the pen drawing on the tablet.
xorg log shows three different variants.
it shows this:

and then there are warnings through out the log like this:

and at the end it goes on for ~4000 lines as I scrolled the pen on the tablet:
(WW) stylus: bad data at 1 v=9e l=9

(WW) stylus: bad data at 1 v=80 l=9

Well it looks like the xorg.conf entries didn't end the initialization problem. Sometimes it does. The one time it initialized is when you got the "stylus bad data" entries. So sort of progress. Was the pointer arrow tracking the pen/stylus with that one?

The one thing you could do is comment out Option "ForceDevice" "Serial". That was only needed with very early versions of xf86-input-wacom soon after the fork from linuxwacom. I'm dubious that will help though.

I think you'll have to contact tokenrove for this. Hopefully he has some time available to take a look.

[Cognuss]

No unfortunatly the pointer arrow doesn't track the pen.
I commented out the Option "ForceDevice" "Serial" but it didn't make any difference.
How should I contact tokenrove?
