[ros-users] NXT Ultrasonic sensor

Hello,
    I am using cturtle from the Ubuntu Lucid repositories, with the svn
version of the nxt stack. I am running Ubuntu Lucid x64 with kernel
2.6.32-generic. I have an NXT controller, and I am trying to use it with
ROS. I have an ultrasonic sensor configured for use on the robot. When I run
nxt_ros with bluetooth, I get the error "nxt.error.I2CError: ls_get_status
timeout" when it is setting up the sensors, and nxt_ros dies. When I use
USB, I get the error "usb.USBError: No error" and nxt_ros dies. What can I
do to fix this? If I comment out the ultrasonic sensor from the yaml file
(and just leave two motors and a gyro), the process runs just fine.
From,
   Max
