Using arduino mega with intel edison mini breakout

Hi, i'm working with reading data from a single board computer , I can read data from an arduino mega in my raspberry pi and beagle bone black, but i can't read this in the intel edison. I'm using 1 usb (j16) to energize with my computer, and the other mini usb (j3) to read from arduino mega. the communication with my computer is using wifi .For testing the serial port, i'm using "cat /dev/ttyMDF1", but this command does not display anything. Am I using the correct port for reading arduino?

Thanks
