I am one of the many who fails to get his arduino started. So I read and tried for 2 hours what I could find on the web. In vain. Here what I did:
- Its an (conected) UNO,
- I have debian squeeze (up to date),
- I installed arduino-0022
- I verified to have librxtx-java (2.2pre2-8) (so > 2.3pre)
- I also put myself to the groups dialout cdrom floppy audio dip video plugdev netdev bluetooth scanner
- and finally, I chose UNO in the tools menu.
of course dmesg recognises my board, and puts it to ttyACM0 which made me try ln -s /dev/ttyACM0 /dev/ttyUSB0
BUT, I does not work, meaning that the selection menu for the serial port remains greyed out.
