ros-fuerte openni.launch unable to find usb device [closed]
Hi all!
I have a fresh install of ros-fuerte. I'm trying to start working with kinekt camera. So, I use:
roslaunch openni_launch openni.launch
But the output contains tons of errors like these at first
Exception AttributeError: AttributeError("'_DummyThread' object has no attribute '_Thread__block'",) in <module 'threading' from '/usr/lib/python2.7/threading.pyc'> ignored
and then I see an error message like this:
[ INFO] [1338745409.467378076]: Number devices connected: 1
[ INFO] [1338745409.467555102]: 1. device on bus 002:04 is a Xtion Pro (600) from ASUS (1d27) with serial id ''
[ INFO] [1338745409.468875705]: Searching for device with index = 1
[ INFO] [1338745409.473786315]: No matching device found.... waiting for devices. Reason: openni_wrapper::OpenNIDevice::OpenNIDevice(xn::Context&, const xn::NodeInfo&, const xn::NodeInfo&, const xn::NodeInfo&) @ /tmp/buildd/ros-fuerte-openni-camera-1.8.0/debian/ros-fuerte-openni-camera/opt/ros/fuerte/stacks/openni_camera/src/openni_device.cpp @ 99 : creating depth generator failed. Reason: Failed to open the USB device!
I've been trying to find any workaround for the whole day, but still no luck. Does anyone have any guesses what may be the problem?
UPD I've managed to overcome the issue by killing XnSensorServer like this:
killall XnSensorServer
So now it eventially found my device:
[ INFO] [1338817322.032348748]: Opened 'PrimeSense Device' on bus 2:4 with serial number ''
[ INFO] [1338817322.055454616]: rgb_frame_id = '/camera_rgb_optical_frame'
[ INFO] [1338817322.055518931]: depth_frame_id = '/camera_depth_optical_frame'
The problem now appears when I try to execute rviz

So there is still plenty of what i don't understand. Does anyone have any ideas how to get rid of those errors?
The threading exceptions are documented here: http://answers.ros.org/question/34304/exception-attributeerror-when-starting-roscore/ and should be unrelated.
Yes, they also appeared on the previous version of ros and still everything worked. the problem is that ros can't see the kinekt camera connected...
Even i have the same issue and am unable to solve the same... any suggestion would greatly help... I did remove the error once but i dunno how i resolved it... ;)
I have similar problem, trying
rostopic echofor the first time after launching openni it works, but for the second it does not, and manager dies with the same error.
