For mine, it's something like the following: <blockquote>crw-rw---- 1 root dialout 188, 0 2009-07-28 08:34 /dev/ttyUSB0</blockquote> In my corresponding /etc/group file, my entry will look like this: <blockquote>dialout:x:18:miketeo</blockquote> where miketeo is the account that I use to program my arduino. You may want to check what’s your group ownership for the USB tty device.
For mine, it’s something like the following:

crw-rw—- 1 root dialout 188, 0 2009-07-28 08:34 /dev/ttyUSB0

In my corresponding /etc/group file, my entry will look like this:

dialout:x:18:miketeo

where miketeo is the account that I use to program my arduino.

Even though I've logged out and back in. I am able to write to the arduino if I run arduino as root, which is kind of a pain. Any suggestions?
