Openni_tracker crushes when openni2_launch starts

Hi, I'm using the Asus Xtion Pro Live with ROS Hydro on Ubuntu 12.10 64-bit. I have a problem with openni_tracker! I need to start both openni_tracker and openni2_launch, but when I launch openni2_launch, openni_tracker gives the following error: "InitFromXml failed: Failed to set USB interface!". If I launch only openni_tracker, it works! Do you know where is the problem? How can I solve it?

@sparksmith answer is likely right. If you need to use openni2_launch to get your Xtion to work at all, you could use openni2_tracker instead. The base repo actually doesn't do much (it seems due to licensing issues with NITE2), but github user @nxdefiant submitted a pull request that mostly provides the functionality of the original openni_tracker.

The other solution would be to get your Asus to work with openni_launch and then use openni_tracker. See my answer here for how you might do that.

Didn't realize the question was a few months old, maybe someone still cares!

to be honest I do... I am currently struggling with openni2_tracker because of problem with orocos and was searching for different things that might help in successfully running any of the possible trackers.

@sparksmith you need to provide the full path to the orocos_kdl package inside your CMakelist. Something like this:

find_package(orocos_kdl REQUIRED) By itself... Then there should not be any orocos path issues. Kinda lame. I don't know what catkin does not figure this out on its own.

Now, how can I run openni2_tracker and openni2_launch at the same time?

At this point, I'm unaware of any solution that allows both to be run simultaneously.
