openni "creating depth generator failed"

edit

Hello,

I just installed the diamondback base and openni_kinect package. Then, if I do

rosmake openni_camera everything was compiled successfully. Then, if I do roslaunch openni_camera openni_node.launch, it says

1 [ INFO] [1310405330.895790349]: [/openni_node1] 1. device on bus 002:06 is a Xbox NUI Camera (2ae) from Microsoft (45e) with serial id 'B00363708464051B' [ INFO] [1310405330.900782094]: [/openni_node1] searching for device with index = 1 [ INFO] [1310405334.914925388]: [/openni_node1] No matching device found.... waiting for devices.

Reason: Got a timeout while waiting for a network command to complete!

like above.

I don't know how to solve this problem,

Can anybody help me with installing openni_kinect and what my problem is???

Thank you
