I am running ROS Fuerte on Linux, and right now I can run one Kinect using roslaunch openni_launch openni.launch, and use rviz to see both the depth and RGB cameras.

How can I get a second Kinect to work simultaneously? I tried attaching a second Kinect to a different USB bus, and lsusb recognizes both, but rviz still only sees the first Kinect when using Pointcloud2.

Thanks!

You'll need to provide some parameters to the second call to roslaunch, so that it picks up the correct device, and publishes the second point cloud on a different topic.

Also, you'll need to put each Kinect on a different USB bus; a Kinect saturates the bus it's on.

You need to run two instances of the driver. Launching openni.launch twice should work. To be able to see both point clouds simultaneously, you'll also need a transform between the root link of each Kinect.
