Asus Xtion live pro on USB 3.0 - ROS-kinetic - Ubuntu 16.04

I tried to use roslaunch openni2_launch openni2.launch to connect my asus xtion pro live.

But i have errors : Warning: USB events thread - failed to set priority. This might cause loss of data.

What may cause this problem?

I use ROS kinetic, Ubuntu16.04, my asus xtion live pro supports openni2 not openni. It seems the answers here are mostly about previous versions of softwares. Anyone encounter such problems in latest versions?

This is only a warning. Your Xtion should still work.

OpenNI tries to set the USB async thread priority to critical. This works on Linux only with root privileges. For a normal user, the program will throw this warning. To get rid of this warning, run the program as root. source

For my knowledge, the Xtion Pro live does not work on USB 3.0. You have to change the firmware. I followed this link https://github.com/nh2/asus-xtion-fix
