No devices connected... Waiting for devices to be connected

edit

Hi,

When I start 3dsensor.launch I get:

[ INFO] [1414430559.252574176]: No devices connected.... waiting for devices to be connected

When I rosrun openni_camera openni_node by itself I get the same error.

I've trawled rosanswers looking for a solution, but nothing's worked yet. : C lsusb lists the kinect; I've followed the suggestions here, and the suggestions here, and the suggestions here, and the suggestions here, and here to no avail.

This is being run on a turtlebot2, and both the turtlebot and the workstation are on 14.04 trusty and indigo igloo. The kinect is plugged into the usb 2.0 port.

lsusb yields:

Turtlebot specs are: Ubuntu 14.04 Trusty Memory 1.8 G Processor Intel Celeron @ 1.50Ghz Graphics intel ivybridge mobile OS type 64 bit

I'm at a loss. does anyone have suggestions?

I'm not entirely certain if it's related, but when I start up my minimal launch I get this:
