[Linuxwacom-devel] driver problems

I've got the driver I'm writing to the point where it's very functional, but
there's a bug in it that folks at the gimp-irc are telling me is quite like the
one experienced by you Wacom folks, described at:

https://bugs.launchpad.net/ubuntu/intrepid/+source/linux/+bug/260675

I'll try to describe it here anyhow ...

My driver, uclogic_drv.so,  is an Xorg Xinput driver, written to run in FreeBSD,
using only USB-HID (no serial protocol, I couldn't find any).   It's all dealing
with working with Gimp.  When you configure it on Gimp, you can set it to one of
3 options, Window, Screen, or Disabled.  If I set it to disabled, then the X and
Y axes seem to work fine, but TipPressure is ignored.  The Device dock only
lists "Core Pointer".

Alternatively, if I configure the driver to either Window or Screen, then the X
and Y indicators in the ruler spaces stop moving, the UCLogic shows up in the
Devices dock, and *IF* I set the 3rd valuator (my tip pressure) to the X axis,
*then* the X indicator in the ruler spaces jumps around in sync with the tip
pressure, telling me that the tip pressure is definitely getting into gimp.  The
regu;lar operation of the 3rd axis (for TipPressure) never works for me.  I
can't tell if TipPressure works OK then because when Window or Screen is
selected, remember, the X and Y ruler cursors stop moving.

I was told, this sounded really like a problem already experienced by you Wacom
folks.  I'm not doing this on Linux, it runs instead on FreeBSD, so the fix in
the URl won't work for me, I need to get a bit more basic.  I'd sure appreciate
any ideas you might have.

Thanks
