It's not as simple as using one of the pre-made USB networking cables. If such a thing exists, a USB null modem would likely work, but you would need 2 USB clients in the hardware between the computer and the stb. Using 2 FTDI USB to serial chips or cables wired in a null modem configuration would likely get you talking, but you need to know the protocol to transmit. There is an LIRC driver available, so there might be enough info out there to do it.
