I believe this to be because a genuine serial port (RS232) and speakup use the hardware hand-shaking pins (RTS and CTS?), to communicate readiness to send and recieve data. The USB to serial adaptors will either not support this hardware hand-shaking or it takes a differently written program to use it.
