Yes.

Here is the evtest utilities I was thinking of earlier: http://cgit.freedesktop.org/~whot/evtest/tree/evtest-capture.txt

The code is capable of creating the code for a uinput device using xsltproc.

I am putting this on utouch itself, since it is not really part of any of the individual packages.

Please see evemu, a kernel device emulation project: http://bitmath.org/code/evemu/.

The aim is to use this package (once in bazaar) to create gesture timing code in grail, which should resolve this problem.

Thanks, Henrik! I've created an LP project for it here:
  https://launchpad.net/canonical-multitouch/utouch-evemu

and a wiki page, based on your original intro email to the MT mail list here:
  https://wiki.ubuntu.com/Multitouch/Testing/uTouchEvEmu

We aim at providing timing code as well, but given the title of this bug, I guess the bug is now fixed.

This one needs packaging...

Bump.

Who's the best person to package this up? Chase, can you assist Henrik?

Henrik, it's not clear to me if you want to package it or if you'd like someone else to package it. I can help package it if you like, especially since I'll be using it for building a test framework.

Either way - I would appreciate the help very much.

Ok, I'll take ownership of the bug and add this to my queue of work.

Henrik was able to get utouch-evemu packaged up before I could even take a closer look :).
