2016-12-07 02:38:57 -0500 asked a question 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?
