After inserting the FTDI device you should get output similar to this: 

usb 1-1: new full-speed USB device number 5 using ci_hdrc
usbcore: registered new interface driver usbserial
usbcore: registered new interface driver usbserial_generic
usbserial: USB Serial support registered for generic
usbcore: registered new interface driver ftdi_sio
usbserial: USB Serial support registered for FTDI USB Serial Device

usb 1-1: Detected FT232RL
usb 1-1: Number of endpoints 2
usb 1-1: Endpoint 1 MaxPacketSize 64
usb 1-1: Endpoint 2 MaxPacketSize 64
usb 1-1: Setting MaxPacketSize 64
usb 1-1: FTDI USB Serial Device converter now attached to ttyUSB0

Start minicom and set the interface: 

# minicom -s
