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
Best regards!
