Startech sucks, buy a keyspan converter

Real bad experience with these guys, where to start.

Their converter never worked with my I mac or my PC, they wanted me to keep trying new drivers. I finally gave up and just threw the piece of junk out. Note that their "manual" is just a tiny and incomplete note, not really helpful and no utilies were included.

By comparison, the Keyspan USB serial adapter worked great, I have two of them on the same computer. It comes with great software, easy to use and understand and allows the user to configure the ports etc. but you need not even do any of that. It is automatic.

So there is no choice, avoid Startech or get screwed.
