Digilent USB 2.0 module

Hi,

I have the Digilent 2SB board and also the Digilent USB 2.0 module (it has the Cypress CY7C68013 FX2 chip) and I want to find a way for communication between a Linux machine and the USB module. I will make also a new firmware for this. I could make the Linux to give it a standard driver like the HID driver but it will be a slow solution.
Does anybody has any idea what kind of driver I could use or ... whatever...

Thanks in advance for any help
