Can't open the device issue

[ewerlopes]

Hi,

I could compile the code normally using catkin_make... However, when I try to "roslaunch" the project I get a "[FATAL] [1467020828.259201654]: Can't Open Device"... despite de fact that the kinect2 device is connected normally to the computer as well as running normally using libfreenect2. Do you have any insight of how to solve this problem?

Thanks.

do you have nite 2.2 installed?

[ewerlopes]

Hi, thanks for your answer...

Yes! I do have it installed!

Well, at least I ran the ./install.sh file previously..

[mcgi5sr2]

Have you tested the Nite2.2 install? using the sample viewer?

Hi, I have the same error when I launch kinect2_tracker. [FATAL] [1504009786.065208239]: Can't Open Device

UserViewer works well!

Can someone help me? @ewerlopes Could you solve your problem?

have the can't open device error too :(

I could solve this problem for my case!

The libfreenect2-openni2.so must be copied in /usr/lib/OpenNI2/Drivers

@Ampul3x Tell me if this worked for you :)

i copied it into /usr/lib/OpenNI2/Drivers too, but im still getting the error ... Maybe there is another problem. When i unplug the kinect v2 i get the same error "can't open device". maybe the device cant be found?

@Ampul3x Does the User Viewer work?

Hi,

I was also facing the same issue while running the kinect2_tracker. I solved it by going through the installation page of libfreenect2.

I had not run the last command given on the webpage (see at the bottom of libfreenect2 webpage). After running the OpenNI2 test, the tracker started working.
