Hi Eric,

Thanks for your fast reply, but unfortunately the error still persist even after changing the owner and the group to the username of the user that i am trying to run the code from.
This is the output that i get after running $ ls -l /dev/*1394*

Output:
crw-rw---- 1 shuttle shuttle 171, 0 2011-02-07 13:42 /dev/raw1394

/dev/video1394:
total 0
crw-rw----+ 1 shuttle shuttle 171, 16 2011-02-07 13:42 0

Subject: Re: [ros-users] Trying to get bumblebee2 to work

2011/2/7 xr tay <wrathy1987@hotmail.com>






Hello everyone,


 I'm using ROS C Turtle with BASE, running on Ubuntu 10.04(lucid) with Kernel Linux 2.6.32-25-generic.


I try to launch the bumblebee2 using: roslaunch bumblebee2 Bumblebee2.launch


However, the following error was generated:


libdc1394 error: Failed to initialize libdc1394

[FATAL] [1297056569.563407417]: [camera] exception opening device: [Camera1394::open]: Could not initialize dc1394_context.

Make sure /dev/raw1394 exists, you have ac


I have tried using these three commands to fix the error:


$ sudo modprobe raw1394
$ ls -la /dev/raw1394  (output is "crw-rw---- 1 root root 171, 0 2011-02-07 13:42 /dev/raw1394")

$ sudo chmod a+rw /dev/raw1394
I usually do sudo chown -R username:username /dev/*1394* where username is the username of the user you are trying to run code from. This lets me use my Point Grey firewire cameras. I found that I usually need permissions on more than just the /dev/raw1394 device, hence the recursive chown.

Hope that helps.
- Eric 


but the error is still there, so i was hoping if anyone have any idea on how to solve this error.


Thanks,
Tayxr
