Arduino 1.0 and Arduino UNO on Debian squeeze (6.0.3)
5. Ofcourse you don't want to be running the arduino ide as root, so add your user to the groups tty and dialout like so:
sudo usermod -a -G tty yourUserName
sudo usermod -a -G dialout yourUserName
Log off and log on again for the changes to take effect!
Debian squeeze, ubuntu, xubuntu
