Anyone using this one? I have one myself. But only got one ps2 controller.
It says in the "read me" "Joytech PS2(R) to USB Controller Convertor (demans that 2 PS2(R)-controller are attached)

Anyone using it with to controllers and it works? Thinking about buying another controller. But wanna know if it really works.

yeah it works. i tryed fifa wit 1 joypad and it goes crazy on the tilte screen. but wen u put 2 in everythin is all good. evythin works fine about from wen u go in2 a the joypad rumble like **** all the time so u have 2 delete 2 files from u directory if u have xp. if u have u can find the post in this froum sumwere on wat files 2 delete

Sure it works.

1) You do need 2 controllers plugged in

2) It does go heywire without a second controller

3) The DualShock does go on constantly as soon as you enter the game :(

I suggest you find a fix first for the (point 3 above) as pazz007 suggested. I will be doing that.
