[ros-users] openni_camera and the /etc/primesense/GlobalDefaults.ini file

I am seriously confused about the role of the
/etc/primesense/GlobalDefaults.ini file in the ros openni_camera
driver. In this thread [1], I was told by Suat that the driver does
not in fact use that file. However, I get different behavior from the
openni driver when I change parameters in the file, leading me to
empirically believe that the driver does in fact use it, or at least
parts of it.

The real confusion sets in when I attempt to change parameters that
the Kinect device is supposed to support. For example, changing the
WhiteBalance and Gain currently has no effect. I find this really
weird, since I do remember being able at one point to turn off auto
white balance by modifying the file.

I also recently obtained a Axus Xtion Live Pro device. I was under the
impression the device should provide hardware sync and registration
capabilities - I have not been able to get either so far. I was told
in the openni googlegroups [2] that both should be available using the
openni API. Is this being handled properly by the ros driver?

I might be compounding different problems here, but any help would be
appreciated in resolving these conflicting opinions and results that I
am getting.

Thank you,
