    fx3 enumerate as UNKNOWN DEVICE in Windows 10 x64 , but ok in Windows7 64


           I designed firmware and programmed the device.

           Win7 can identify it as my design name, and device(my firmware has been programmed already ) can be installed the driver.

           W10  identify it as UNKNOWN DEVICE, I can't  install the driver. In W10 , the VID & PID always be correct.

           When FX3 boots without any firmware , it will be identified as "Cypress WestBridge " in W10 if it has no driver, and it can be installed the defualt CY W10 driver successful.

           So, the problem must be in firmware , but I have no idea about this.

           How can I solve the problem ?


      Best regards.
