usb-usb port

hi guys i realy want to conect two computers with bridged usb-usb port.
my both computers support usb 2.0...but i can't find the bridge schematic...
pl-2501 05082c is the bridge chip used.... as far as i could see on the internet
i want to do this by my self...not just to buy it in a store.
so i will be appreciative if some of you help me do it...

there's an actual software for doing this usb superlink.

check this out **broken link removed**

so there is no way making the bridge home and simply download software...ok thanks a lot you saved my time
