Urrr, you don't... USB dosn't have RTS/CTS etc..
It has four wires, +5V, Ground, -Data and +Data. USB is a synchronous serial interface, not asynchronous like RS232. You could think of it being more like an Ethernet port than an serial port... That means that setserial probably has no idea what to do with it...
