I have recently bought a Virtex-4 LX25 evaluation board from Avnet. It has Cypress FX2 chip for USB 2.0 communication support. The generic USB driver provided by Cypress is of no use to me. Whenever I connect the USB of the board with the PC, the immediate message is "Unknown USB device". This happens because the VID and PID of the device received at the host is 0. I have tried installing the driver with EZUSBw2k.inf as well as CyUSB.inf but none has worked. Is there any body out there who has used the FX2 with Cypress provide generic USB driver? If someone has used USB with an Avnet board, that will prove very helpful to me. Looking forward to a sound advice. Thanks.
