Altera DE1 project

Hi guys,

I am doing my final year degree project using the Altera DE1 board. My project requires a USB communication from a computer to the FPGA. It must be a two way communication whereby I must send some data down the USB and receive data through it as well. I understand that I am able to use VB or C to come up with programs to control the USB but can you guys suggest how can I make the interface between the computer and the DE1 board? Is the any megacore function that I can use?

Appreciate your help very much.

Cheers!
