You can connect that to a laptop or other modern PC without a serial
port, in order to get a serial port which applications can use. You
also need a cross-over serial cable, not just a gender changer.

However, that USB thing is only useful on the host system, where you
do development, compiling, save logs, and so on. It is not useful on
the target side. There you must have an onboard serial port.
