Can't get Ubuntu to see FTDI cable for breadboarding Arduino project I am in the process of breadboarding an Arduino for a project and am using my FTDI Serial cable Adafruit FTDI Cable (tested working on Windows 7). I have also tested the breadboarded Arduino successfully on Win7.

When I plug the FTDI Serial cable into my Linux (Ubuntu 14.04 with Mint Desktop) laptop and the other end to my project (exactly as I did for Windows and it works for Win7), the Tools, Port is grayed out when in Linux.

I have tried running Arduino as root, with no success.

The output of : dmesg | tail is

sudo dmesg | tail
[  729.069015] usb 4-1.2: New USB device strings: Mfr=1, Product=2,     SerialNumber=3

When I type "lsusb" into the terminal, there is no difference between when the FTDI is plugged in and not plugged in.
I have tried switching ports with no success.  

Any suggestions?
Check if the driver is loaded, in Terminal type: 

lsmod | grep  ftdi_sio


If you get no answer then it's not loaded, load it using:

sudo modprobe ftdi_sio


I hope this helps.
