[ros-users] bumblebee problems

I am trying to use the bumblebee2 package but i have been having problems
when i type: rosrun bumblebee2 bumblebee2 _video_mode:=1280x960_mono8

It shows: [FATAL] [1308301263.420322694]: [camera] exception opening
device: [Camera1394::open]: Unable to get iso data; is the camera plugged
in?

but when i type rosrun camera1394 _video_mode:=1280x960_mono8 works
correctly

I am using Bumblebee XB3 BBX3-13S2C
Can anybody help me?

Thanks in advance
