I installed the arduino software through synaptic on linux 10.04
I can't access to the menu Tools -> Serial Port , it is greyed out When I tried to upload it said "serial port 'COM1' not found" I checked the forum and found this http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1245954593/0
I followed their advice, I added myself to the "dialout" group I edited the preferences.txt in the .arduino folder to "serial.port=/dev/ttyUSB0"
now the error when uploading is "Serial port '/dev/ttyUSB0' not found"
if I run the arduino software as root, it works fine (the menu isn't grayed out , I /dev/ttyUSB0 is checkeda,d I can uplaod stuff) but I would like to make it work without being root
this is what I get when I do ls -l /dev/ttyUSB0
$ ls -l /dev/ttyUSB0 crw-rw---- 1 root dialout 188, 0 2010-08-21 20:29 /dev/ttyUSB0
