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. > That means that setserial probably has no idea what to do with it... 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.
