Consider using an FTDI (USB) chip. FT245x USB to parallel converter chip (http://ftdichip.com/products/ft245r.htm) is a good choice.

It allows bi-directionnal transfer between PC and FPGA.

Bandwidth is very good (near 12 MBits), and the chip is *VERY* easy to interface.

On the PC side, Windows DLL provided by FTDI is also easy to use and well documented. In a couple of day, you shoud be done.

This is the chip used in the Altera USB-Blaster.

Hope this helps.
