Oops, try /dev/input/event[whatever the event number is], maybe it work 
with symbolic links (like [hid]).  I don't have an ubuntu machine 
around, so I can only give suggestions, but you'll find a ton of posts 
about this topic in pd and linuxwacom mailing lists.
thanks for the sugestion, 
using event[number] is exactly the same than using the symbolic link


i think i will plug my wacom on an other computer, and use gemmouse to get it's 
data...
it's a bit crappy, but it should be very easy...

thanks

You are probably having the same problems that I was having before I 
purged my system of udev/hal.




I agree, getting a tablet to work properly in pd has become a pain 
(worse in OS X and windows), but once you do, it makes for a great and 
cheap controller. 
Arg.. there was one post that I followed exactly on the ubuntu forums on 
how to get rid of hal, but I can't find it :(  But, maybe this isn't the 
best way anymore, maybe they got things working correctly. The 
linuxwacom list is really helpful and always got me on the right track 
(since the problems were changing as rapidly as Ubuntu).

One thing to try; do you get any tablet data output using wacdump?

I'm not in front of a Linux machine at the moment, but I was using a Wacom
tablet in linux for the last couple years.  [HID] doesn't work with calling
the symbolic links in /dev/input/. I was able to get the tablet to send out
data with [hid] by going through the [open $1( with all indeces, clicking on
[info(, then seeing if it was the tablet.  I tried various ways to automate
this with the output info strings but never got anything to work
consistently.  This, and that I didn't like the way control data was output,
made me switch back to using [linuxevent].  It works just find with [open
/dev/input/wacom ( and the data is easy to interpret in pd.  I attached a
(very dirty) patch that I used to route the control data with [linuxevent],
hope it saves you some time.

Tablets don't seem to work well with [hid] in any platform (not in windows
either, right?), not at all in OS X, the platform I am now on.  I'm
re-writing a general purpose [tablet] external right now that will at first
only work in OS X, but hopefully it can cover all platforms later on down
the road.  It is just that the API is different for the three big ones, mac,
linux, and windows.

You are probably having the same problems that I was having before I purged
my system of udev/hal.

I agree, getting a tablet to work properly in pd has become a pain (worse in
OS X and windows), but once you do, it makes for a great and cheap
controller.
Arg.. there was one post that I followed exactly on the ubuntu forums on how
to get rid of hal, but I can't find it :(  But, maybe this isn't the best
way anymore, maybe they got things working correctly. The linuxwacom list is
really helpful and always got me on the right track (since the problems were
changing as rapidly as Ubuntu).

 hello,
 i'm running the last ubuntu (9.10), using kernel 2.6.31

 hum, i don' really want to spend lot's of time tweaking stuff. it is sad to
 realize that using a wacom use to be very easy but it is no more...

 sudo wacdump /dev/input/wacom gives me a segmentation fault...

 thanks for your help

 What distribution are you running?  In the newer Ubuntu's (ex Jaunty), I
 had to do all sorts of things to get back the old (and working) xorg
 configuration and stop using udev.  I have a ton of posts about this on the
 linuxwacom-discuss mailing list and probably this one too, I think I was
 having the same problems as you were then, and finally got it fixed (right
 before my laptop was stolen and I bought a macbook :).  It may work better
 now, probably with more tweaking, as that was 1/2 a year ago.


 One thing to try; do you get any tablet data output using wacdump?

 Good luck getting it working, I'll try to help more if I can.

argggh.
your are right : pd did not have permission to read the input device.

starting pd as root help a bit : now both linuxevent and hid can
open the device.
but they does not send any data...



thanks

Does pd have permissions to open /dev/input/wacom (or any of the
event*'s)?

   The problem that I had with /dev/input/even* devices is
that it
   always changes when you unplug/replug your tablet.
/dev/input/wacom is a symbolic link to the newly created
input,
   no matter what event* it is.

  [hid] uses the input.h struct, which the

 Try using an
  /dev/input/event* device.

  playing a bit more with that object made pd to crash.

  any suggestion to make my wacom work with hid?
