USB Serial Devices and Speakup

As far as I know, speakup will not drive a synth connected via a
serial to usb converter. This is because the addresses used by usb are
different then the addresses used by standard serial ports. There is
also the fact that the uarts in serial to usb converters differ from
the standard 16550a uart in a standard serial port as far as I know.

Since cvs speakup is now modularized, I was wondering for some time
now if it might not be possible to drive a usb to serial connected
synth, assuming that the synth driver in question was loaded as a
module after the usb system came up, and if the serial synth module
could accept i/o addresses as arguments. There would  of course be the
problem of the different uarts, although I suspect that could be dealt
with in some way as well. How about it Kirk? Would this be possible to
implement? If so, then I just might play with speakup serial code, and
see what I could figure out.
