Mega 2560 sketch upload problem

Development Tools IDE 1.x
1

This the first time I use Arduino board. I tried to upload the blink sketch (built-in examples) to a new Arduino Mega 2560 but it didn't work. Mega 2560 is selected at 'Boards' menu but I can't select the serial port because the 'Port' menu is disabled. the Arduino functions normally when connected to USB port of the computer: the green LED is on and pin 13 LED blinks.

I use Arduino 1.6.6 and ubuntu 14.04 (64-bit).

After trying to upload, I get this message:

Thank you for help.

Where did you buy the board from?

Sounds like the usb-to-serial chip isn't being configured properly by linux on connect.

3

The board isn't mine. I'm not sure whether it is original. How to configure usb-to-serial chip properly?

4

Identify what USB to Serial chip the board is using.

5

It features the ATmega16U2 programmed as a USB-to-serial converter.

6

Check if any try.usbmodem devices are created when plugged in.

If so, you made need to add your user to the dialout group or run the IDE with su.

7

No, there aren't any devices created (ttyUSBX or ttyACMX) when plugging Arduino. Plus, results are the same by runnig IDE with sudo. I don't know what is the dialout group?

Sounds like the 16u2 needs to be reprogrammed.

Look at this one:
