Hi Hartley,

Please send i2c-specific questions to the linux-i2c list, as specified
in MAINTAINERS.

No, it works reasonably fine. I was using it myself no later than one
month ago. Out of curiosity, with which exact evaluation module do you
plan to use it?

No. What is broken is input-utils' upstream. I tried submitting patches
2.5 years ago:
  http://sourceforge.net/tracker/?group_id=3063&atid=303063

As you can see, nobody took care of them. Apparently I then did not
even bother sending the one adding support for the TAOS EVM.

The patch in question is still applied to the openSUSE version of the
input-utils package. If you have access to the openSUSE build system,
you can see it here:
  https://build.opensuse.org/package/view_file?file=input-utils-add-taos-evm-support.patch&package=input-utils&project=openSUSE%3A11.0

In case you don't, I'm attaching it too. I might add it to the patch
tracking system on sourceforge too. Not that I really expect upstream
to pick it in a timely manner, but at least other distributions would
see it and may decide to include it.

Hope that helps,
