Dude, I JUST fixed my controller problem a week ago. I've been looking a for a good PS2 > USB adapter for Final Fantasy 11 for a while, and it seemed like the only place you could get them was ordering from China or something. I got one on ebay that advertised it working with XP -- but it only worked in 98.

Then I saw that Radio Shack actually has these. Its about 11 bucks and works like a champ, including rumble function. This is it.. I'm extremely satisfied. Ha ha, I seriously havn't been this stoked with a purchase in a looong time.
