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.

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.

              hello

              few years go, i used a wacom with the [gemtablet] object.
       this
              was working perfectly.
              but i now realize that this object is no more part of Gem
       (since
              3 years).
              the dummy object that replace it say that one must use
       hid instead.
              so did i.

              but i failed making it work.

              i'm using linux and hid from pd svn.

              i send a "open /dev/input/wacom" message to the hid
       object, and
              get as only answer : info: open 0
              info: device 0

              if i start pooling, then the wacom did not work anymore,
       and i
              have to reboot the computer to make it work again.

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

              any suggestion to make my wacom work with hid?
              any other object that could get data from a wacom?
              or should i try to get the old sources of gemtablet to
       compile
              again???

              thanks
