I installed ROS on both the Robot (netbook) and the desktop computers after installing UBUNTU.

I am running a roomba, but not a 5XX or a create. I just need to CHANGE the port settings.

I tried to change a file by gedit which was supposed to have the tty,usb0 inside. Once I changed it, it would not let me save it because I did not have permissions.

I have read the manuals and tried every which way to change it. Once I can see the port on the roomba and the kinect, then I can start doing the turtlebot, etc.

Any ideas welcome.

There is a parameter to set the port for the node. This is a much better solution than editing the code installed on your system. The parameter is ~port. See the turtlebot_node wiki page

If all you have to do is edit the file, could you just access it as an administrator with the sudo command?

sudo gedit

This is the fix for your stated question. However it is not recommended to modify things installed onto your system. Instead you should consider using a source checkout.
