I have only used a USB to serial in Windows.
But I thought that others had done it after the computer had gone through
its initial screens.

No, speakup and the Apollo, or any other hardware speech-synthesiser
will not work with a USB to serial adaptor.
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.
