Just wait! The market for USB->Parallel adapters is going to explode!  (;

That may be a too simple way to see things, but almost every high level players play SFIV with a USB fighstick (ps3 or xbox). I have never heard anyone complain about the lag of the usb interface.

In my experience with the different ports, USB is just easier. Honestly most of my audio equipment is firewire and I prefer that, but usb is great for this kind of thing - it usually just works, often without the hassle of installing drivers.

I have different experiences with the LPT port - more often than not, I have found that using this port causes major issues when hibernating the computer. With some of my gear, using this port prevents the computer to shut down or hibernate. With other gear, upon re-awakening the con nection is lost.

Not so much experience with the com port.

The point I am interested in is to find out the real numbers, the frequencies at which these ports and controllers operate, maybe that's all fine after all, I have no source to confirm either way and I'm lazy to test, but what I do know is that this interface simply can not have any of those problems, it's perfect!

The points you might be interested in, besides being cheap, fast and perfect, is that even though you may not notice.... if you fail to jump over barrel in Donkey Kong you would know it is only you to blame, and not Windows or some keyboard controller for reporting your jump one frame too late. In other words, it would make the game more "legitimate" and probably easier too. You would not want to be failing to break some high-score just because you can run the game at only 12 FPS, right? This would be almost exactly the same, just need to find out how bad or not bad it really is. -- Don't forget that USB can be set up to probably 1000Hz, so perhaps your friendly neighborhood Driver-Man can solve the problems if it turns out there are any. My name is not Driver-Man becasue I drive a truck, but becasue I make drivers.

Osirus23:
A USB interface polls at about every 0.002 seconds. The screen (at 60Hz) refreshes every ~0.0167 seconds, with lower framerate games being a higher number yet. Anyone trying to excuse their gaming mistakes on an inferior interface is just kidding themselves.
