Do you remember when I told you to add yourself to uucp group?. I will try to explain your problem.
You has no rights, but if you, as root user change the permissions to 666, then you can get access. This was what you did, and must to work while device is connected (theoricaly). The problem is that when you disconnect the device, its entry in the /dev directory is deleted too, that is: the device are created on the fly by the kernel. Next time when you connect the device again, a new entry is created, but its permissions are de default, then your 666 trick doesn't work. Of course you can do the trick as many times as you connect the device but you need to switch to root user and is very tired. The solutions are: 1) Switch as root user and run whatever you want because root has no restrictions. This is valid but insecure as nature. You convert linux in windows (yuck). 2) Switch as root user when device in connected and type the command: ls -l /dev/ttyUSB0 and you must to get something like: crw-rw---- 1 root uucp 166, 0 2009-11-17 21:30 /dev/ttyUSB0 that show to you in this case that root user and uucp group users has enough rights to read and write to /dev/ttyUSB0 device. That is the reason I told you to become uucp group member. You have Ubuntu and your group can be different, check it, become member, and problem solved forever.
