I got the impression that Vik was asking about one of these serial-port
adapter things with DB9 connector (I'm talking hardware here) which
hook up to a USB port. In other words, they turn a USB port into a
serial port. A few months ago I was wondering that myself, and thought
that it would require special serial drivers which know that there is a
USB in between, and that getting a PCI card with a serial port on it was
going to be faster.

I'm afraid that seems likely. These kind of programs assume a certain
kind of hardware, and they don't expect that there is a USB bus in
between. I might be wrong - I'd like to know too.
