ubuntu tries to access the kinect when you plug it in in newer versions using a mod. Go to terminal and type,

sudo rmmod gspca_kinect

and you should be good (it does this every time you connect the device). There are other troubleshooting methods on the OpenNi Grabbar Framework page

EDIT: If this is your problem, blacklist the gspca_kinect module on your system,

sudo echo "blacklist gspca_kinect" >> /etc/modprobe.d/blacklist.conf

No it doesn't work, ERROR: Module gspca_kinect does not exist in /proc/modules

any other ideas??

After plugging in the kinect? Is the XnSensorServer running after connection? (try 'killall XnSensorServer' into terminal, it's another prime sense executable attempting to access the kinect). If the gspca_* are not mod's then I don't think the kinect is transferring data to your port

already tried killall XnSensorServer and no process found.

XnSensorServer and the module gspca_kinect should run when you connect the device if all packages were installed correctly. I would double-check the hardware by finding another method to ensure the connection is correct,

I just know that on windows 7 with the official sdk, this kinect works. anyway I've just noticed that when kinect is connect to win has the little light always on, when is on ubuntu the light is blinking. so maybe you're right.

is it possible that I ve not installed correctly openni?? http://www.ros.org/wiki/openni_kinect I was checking here, sudo apt-get install ros-fuerte-openni-kinect ..I think there is just this to do or not? cause I've tried to do the lines hg clone https://kforge.ros.org/openni/drivers but I get err

You tried 1. 'sudo apt-get install ros-fuerte-openni-launch' 2. 'sudo apt-get install ros-fuerte-openni-camera' 3. 'rosmake openni_launch' 4. 'rosmake openni_camera'? If connection did not work after that I've got nothing. Blinking light doesn't matter - mine does too

ocli gravatar image ocli  ( 2012-05-29 17:29:08 -0500 )edit

possibly try 'sudo apt-get install --reinstall <package>' both those packages, and then rosmake them again, you might have some more luck

after all day trying don't know why but at the end it works, I reinstalling package,trying in my pc, other pc, other kinect (and hey xbox kinect works, pc vers no), but it works just once then I have to restart ubuntu to make it works again. better than nothing =)
