1  Using Arduino / Installation & Troubleshooting / Re: Can't upload to Arduino Mega 2560 on: November 13, 2012, 02:00:36 pm
I am having a very similar problem with a SainSmart Arduino Mega 2560.  However, the arduino loader is not able to find the /dev/tty.usbmodem1d11 .

Are you able to find this port when you plug in the Arduino with the usb cable?

When I use an Arduino Mega from "Arduino" the port is correctly found and it works perfectly.

I have seen a thread saying that the usb cable can be finicky but I haven't been able to tweak the cable to get a different result....  smiley-confuse

Hi all,

I recently bought an Arduino Mega from SainSmart:

When I try to load any of the examples I get the "Serial port /dev/tty.usbmodem1d11 not found." message.

I have also tried working with an Arduino Mega 2560 from Arduino and it works perfectly.  It easily finds the /dev/tty.usbmodem1d11 and loads the examples with no difficulty.

Any advice regarding working with this board would be much appreciated!
