Hi ROS-users, a new patched version of the OpenNI driver is available: OpenNI 1.5.4.0 Sensor-primesense 5.1.0.41 Corresponding debs can be found on Jochen Sprickerhof's launchpad: https://launchpad.net/~v-launchpad-jochen-sprickerhof-de/+archive/pcl This update fixes a bug that might occur when operating multiple devices the same time and also fixes the XnSensorServer crashes under Ubuntu Precise. Furthermore, we noticed improvements in start-up speed. We'll update the official ROS openni-dev debian beginning of next week. It would be great, if you could give it a try and we are looking forward to receiving your feedback. Best regards, Julius
