The Linux kernel of your host system will create a virtual serial device called /dev/ttyUSBx where 'x'
is a sequentially assigned number. If you don't have any other USB serial converters attached to
your machine, the device name will be /dev/ttyUSB1. You can use your favorite terminal emulator
(minicom, cu, zc, …) just like for any other/real serial port.
JTAG and Serial can be used together.

ftdi_sio 5-1.3:1.0: FTDI USB Serial Device converter detected
ftdi_sio: Detected FT2232C
usb 5-1.3: <strong>FTDI USB Serial Device converter now attached to
ttyUSB0</strong>
ftdi_sio 5-1.3:1.1: FTDI USB Serial Device converter detected
ftdi_sio: Detected FT2232C
usb 5-1.3: <strong>FTDI USB Serial Device converter now attached to
ttyUSB1</strong>
usbcore: registered new interface driver ftdi_sio
ftdi_sio: v1.4.3:USB FTDI Serial Converters Driver
Without the patch the driver will detect and configure two USB Serial TTYs. You should only use
the second one. Since the first one uses the same signals on the FT2232 Channel A shared with the
JTAG.
You may damage your hardware!
