"002" is not a recognized format for device_id. Examples are given in comments in the openni_node.launch file.
The easiest way to get up and running is to use device IDs "#1", "#2", etc., which opens the first/second enumerated Kinect. Another format, closer to what you're trying to do, is "2@3", which opens the device on USB bus 2, address 3. Enumeration order and USB address can both change when you unplug/replug a Kinect however.
To make your launch configuration repeatable, use the Kinect serial number as the device_id. The driver prints the serial number to console when you open the device, so you can collect these by opening with "#1" etc. It'll look something like "B00367707227042B".
