[SOLVED] From where i could find Mother board slot addresses and pin information

Hi
i have designed card using pic. the card can communicate with PC ,now i am thinking about changing my designe so the card can fit into the motherboard slots.
but how can i get information about each pins inside one slot.
i need to know where is the +5volt,the ground ,the port addres so i can send numbers to those ports
i have search several motherboard manufacture and could not get those information.
any hints ?

I think much cheaper to use USB interface than PCI interface.

It is a good idea to use something better, faster and cheaper, frankly I have never done a project using usb cable
But it seems worth the effort, could you direct me to a project that is done using usb, at least what should I need
1-what type of pic?
2- As far as I know there is no command in c# language (Visula stodio ) which could send number through usb cable
Microsoft did not added such a command to its c# language ,they are talking about readding a book by Jan axelson (this is the most important step),do i need a driver ?

still need help

Good sugesstion
i have browsed the datasheet using several searching word(distance,how far,range) findding for how far it can send is important to me. i will close this post soon as solved,but if you know for how far it can send inform me either here or as a porivate message.
thanks

About distance you can check USB specifications
