root

Since i updated from 10.04 to 12.04, i am unable to acces the device connected in /ttyUSB0 if i dont have root access. To be more specific, i use a usb-to-serial com port converter to acces and configure Cisco equipment with a software called Putty. It happens that, since i upgraded to 12.04, Putty only sees the connected device when i run it as "gksudo putty". If not, it says "unable to connect to port /ttyUSB0". I have managed to change the permissions via chmod 666, and it works, but if i disconnect the usb and reconnect, it goes back to root only. How do i permanently allow non-root access? I have a clue it might be via udev rules, but i have NO IDEIA how to do it.

obs. Manufacturer and drivers "PROLIFIC"
