Since I updated from 10.04 to 12.04, I am unable to access the device connected in /ttyUSB0 if I don't have root access. To be more specific, I use a usb-to-serial com port converter to access 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 idea how to do it.
obs. Manufacturer and drivers "PROLIFIC"
