Comment 21 for bug 368135

I have a very similar problem with a 3M Microtouch EX-II touchpanel. It works with the evtouch-driver (Ubuntu 9.10), but after a short period of time (especially if many clicks are produced) the system freezes. I am using the following (custom) fdi-file in /usr/share/hal/fdi/policy/20thirdparty/ :

<?xml version="1.0" encoding="ISO-8859-1" ?>
<deviceinfo version="0.2">
  <device>
    <match key="info.product" contains="3M 3M USB Touchscreen - EX II">

      <merge key="input.x11_options.SwapX" type="string">1</merge>
    </match>
  </device>
</deviceinfo>

Unfortunately the touchpanel does not work when SendCoreEvents is turned off.
