USB vs ps\2 style interface
met365784:
I'm building an arcade controller for a friend and noticed that both I-pac and Hagstrom both offer USB sollutions. What are the advantages\ disadvantages of using USB over PS\2.
Mike:
I don't have the usb version but i have the ps2 version of the ipac. It works fine in all games i've tried including mortal kombat and street fighter. So i guess the only advantage is if you'd rather it be usb.

I guess I should have been a little clearer, I have and use a ps\2 style encoder and I am happy with it, I am concearned about any limitations that may be present in a usb style encoder, ie max key push at once, problems setting up trackball, ect.
Mike:
The encoder it self would be the bottle neck in the number of keys you can hit not the style of connection. You can think of it this way a key stroke would be about 2 bytes of data. A ps2 port is faster than serial. You know you transfer roughly 1200 bytes/sec across a non multiplexed serial connection. So unless you hit 600 Keys a second you won't notice a difference.

USB makes it plug an play. If you make removable control panels it is a must.
