Problem with Serial Port Arduino mega 2560 (MAC)

Hello everybody!

I'm beginning in Arduino, just received my arduino Mega 2560 etc.
I was trying it and when I wanted to upload my project, I didn't find a appropriate serial port... I searched on the linked that was given to me (https://www.arduino.cc/en/pmwiki.php?n=guide/troubleshooting#upload) and i saw that the problem could be from my USB HUB.

I plugged everything directly on my computer (Mac OS X 10.9.2; Intel Core I5; 16Go DDR3) yet the upload still doesn't work because of the serial port..still not appear...

Could you help me? I put a photograph of the circuit :wink:

Best regards!

From the looks of it I'd say your "Arduino MEGA 2560" is a cheap clone. You need the driver for the USB to Serial chip used on your board.

Thanks for the answer! Where can I find it?

Read the part number on the chip near the USB connector and Google for it.

I have Atmega 2560 CH3400, i suppose it this? Thanks for everything^^
