How do identify an Arduino counterfeit?

How can I set the right serial port of my Arduino UNO on linux?

  • I bought a new Arduino UNO, and I inserted in my Linux computer. I installed Arduino IDE and set the board to Arduino UNO just now. I opened an example, and up load it to my board. And I got a message like this: What should I do?

  • Answer:

    Type ls /dev/ttyUSB* /dev/ttyACM* in terminal to see if your device is properly connected or not. It appears that your linux distrbution no longer supports the definition of a com1 you need read write access to serial device file in  /dev/tts gpasswd -a user uucp In arduino-1.0/lib/preferences.txt  change serial.port=COM1 to serial.port=/dev/ttyACM0 and restart your system.
