Libfreenect won't install properly on 12.04 Hydro

Kinect

asked 2014-10-19 17:33:06 -0600

I am trying to use libfreenect with a kinect. The output when I run

roslaunch freenect_launch freenect-xyz.launch

[ INFO] [1413756004.829132537]: Number devices connected: 1
[ INFO] [1413756004.829250239]: 1. device on bus 000:00 is a Xbox NUI Camera (2ae) from Microsoft (45e) with serial id '0000000000000000'
[ INFO] [1413756004.831311636]: Searching for device with index = 1
[ INFO] [1413756004.843299915]: No matching device found.... waiting for devices. Reason: [ERROR] Unable to open specified kinect

The next command I ran was

rosrun libfreenect glview.

This returned

[rosrun] Couldn't find executable named glview below /opt/ros/hydro/share/libfreenect

So I tried

alex@alex-OptiPlex-GX620:~$ rospack find libfreenect
/opt/ros/hydro/share/libfreenect
alex@alex-OptiPlex-GX620:~$ cd /
alex@alex-OptiPlex-GX620:/$ cd /opt/ros/hydro/share/libfreenect
alex@alex-OptiPlex-GX620:/opt/ros/hydro/share/libfreenect$ ls
package.xml

From my understanding this means the proper packages that should come with libfreenect have not been installed. I have tried re-installing with no success. I have run

sudo apt-get update
sudo apt-get dist-upgrade

I have made sure to run

sudo modprobe -r gspca_kinect
echo 'blacklist gspca_kinect' | sudo tee -a /etc/modprobe.d/blacklist.conf

The kinect is being connected by USB 2.0. The result of lsusb is

The issue is the model of the Kinect itself. Version 1473 is currently experiencing issues with the freenect library. Furthur discussion here: https://github.com/ros-drivers/freenect_stack/issues/12

dpkg -L ros-hydro-libfreenect shows that glview is installed into /opt/ros/hydro/bin/glview

Since this is the ROS bin directory (which is added to your PATH), this means that you should be able to run glview without rosrun:

. /opt/ros/hydro/setup.bash
glview

Yes, that does work. It outputs

Kinect camera test
Number of devices found: 1
Could not open device

Do you have any tips why it is unable to open the device?

See my first example as well

The permissions for your device are probably not set properly. The Ubuntu packages include a udev rule that should set up the permissions properly; try sudo apt-get install freenect

Your tip has led me to try some other methods, none of which have worked. I tried

sudo chmod o+w /dev/bus/usb/001/010 /001/010 being the bus and device of XBox NUI Camera.

I also tried nano /etc/udev/rules.d/70-persistent-net.rules as replacing "SYSFS" with "ATTR" should help.

kinect_guy ( 2014-10-20 16:04:20 -0600 )edit

The above directory looks like (for the USB device):

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:21:2f:30:79:c4", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan0"

PS if it wasn't clear I did try your suggestion.

kinect_guy ( 2014-10-20 16:08:16 -0600 )edit

no... that's the udev rule that ensures consistent naming of your wireless interface. You probably shouldn't mess with it.

ahendrix ( 2014-10-20 16:47:37 -0600 )edit

http://openkinect.org/wiki/Getting_St... describes how to set up the udev rules manually.

ahendrix ( 2014-10-20 16:49:22 -0600 )edit

This does not work either. glview still cannot open the device. I tried restarting, ensured the proper kernel is blacklisted and the normal user directory was correct. Any other ideas are appreciated.

Is there a way to manually change the kinect to index = 1 like freenect_launch is looking for?

kinect_guy ( 2014-10-20 17:06:02 -0600 )edit

What are the current permissions on the USB device? Try ls -l /dev/bus/usb/001/
