How to connect from USB port to RJ45 console device?

In my Linux laptop, the USB port is connected to an external router with console port (RJ45, Juniper SRX210). This is the cable i am using:

I used cuteCom And i used minicom

To connect using 9600 but it does not recognize /dev/ttyS0. Also tested with USBViewer (http://www.kroah.com/linux-usb/) which gives error “can not open the file /proc/bus/usb/devices”

How can i make this connection successfull? Here is my lsusb and lsusb -v
