    QTUI2C USB Device not found error

    judson.porter

       Hi all, thanks in advance for the help. I am trying to configure the CY7C67300 (EZ-USB) on a Xilinx XUPV5 FPGA board. I am just trying to run the de2 design example to setup the FPGA as a peripheral. When I try to program the EEPROM with the bin file using qtui2c I get the error "USB Device not found". I assume this is because I am not using the correct driver? Currently the part is loading cyusb.sys that I got from http://www.cypress.com/?rID=34870. The documentation says I have to use cyusbgen.sys, however I am on Windows 7 x64 so I can't get this driver to load. Is there another driver that I can try, or a way to get this to work with cyusb.sys? Thanks.
