[ros-users] openni_camera doesn't find my Kinect

Hi,

it took me a bit to get openni_camera compiled on my Arch Linux box. It compiles and runs now, but it doesn't find my Kinect:

...and there it stays. I haven't found anything about this on the web or on answers.ros.org; seems it works for everyone out of the box. I've tried two different Kinects and several different USB ports on my machine. Can anyone please help me or offer some ideas on how to diagnose this?

Thank you very much in advance!
