razor_imu_9dof dies

edit

I'm having problems running the razor_imu_9dof package.

Diamondback on Ubuntu 10.04

roslaunch razor_imu_9dof razor.launch

Initial problem of not finding ttyUSB1 was edited to ttyUSB0 in razor.launch and node.py files.

I start razor_imu_9dof with my Razor board connected, the two visualization windows come up on the screen, and it may or may not run for a few seconds (watching graphics and rostopic echo /imuRaw), and then the process dies. Graphics stay up, node dies.

Traceback (most recent call last):
  File "/home/turtlebot/ros_workspace/razor_imu_9dof/razor_imu_9dof/nodes/node.py", line 73, in <module>
    line = ser.readline()
  File "/usr/lib/python2.6/dist-packages/serial/serialutil.py", line 60, in readline
    c = self.read(1)
  File "/usr/lib/python2.6/dist-packages/serial/serialposix.py", line 320, in read
    buf = os.read(self.fd, size-len(read))
OSError: [Errno 11] Resource temporarily unavailable
[node-1] process has died [pid 2964, exit code 1].
log files: /home/turtlebot/.ros/log/cc609c80-8b2d-11e2-b23a-0016ea6f4f4c/node-1*.log

other messages like "out of range" and literal for float() also occur. the output from the Razor is clean as viewed on the Arduino IDE serial monitor, and will run forever.

Any thoughts?
