USB events thread - failed to set priority ... Number devices connected: 2

[GianMeng]

Hello, I got a problem when I tried to
roslaunch openni_launch openni.launch
with kinect v1 on my ubuntu16.04

#-------------------------------------------------------------------

The main problem is
Warning: USB events thread - failed to set priority. This might cause loss of data...

It showed the computer connected to two kinects. But I only had one kinect connected.

I Have asked on ROS ANSWER, here, but I get no reply.

So I have to ask help from here.
I hope someone would help me with the issue. Thank you so much.

After a lot of struggle, I finally found an answer which solved the issue. Hope it helps you too.

In "SensorKinect/Platform/Linux/Redist/Sensor-Bin-Linux-x64-v5.1.2.1"
Uninstall the driver - sudo ./install.sh -u
ros-drivers/openni_camera#54 (comment)

Thanks a lot @srisadhan for this solution. I had been stuck with this for over 24 hours, uninstalling and installing everything again but nothing worked.
After uninstalling the driver, openni_launch file started working.
