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.
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).
