Also a quick fyi... I got the aforementioned PS2 USB adapter from radio shack, and I've not regretted it one bit. I did have one little bit of difficulty though that I thought I would share. Running windows XP, the system automatically detected and installed the controller as soon as I plugged it in. However, I was having a hard time getting the rumble function to work and I wanted to use it for fishing at the time (old fishing system). Everything worked except the rumble with the windows driver. I ran the floppy that came with the disk though, and that fixed it.
I know... I was dumb for not installing it in the first place, but I just thought somebody else may have the same problem.
Good luck!
