       Hi,

         

      does anybody know why the OS win 8 64bit is telling device supports higher speed at a SS PORT. Althoug the device is connected to FX3 through USB3 SS port and device is signalling SS speed with the SDK function CyU3PUsbGetSpeed?

         

      The FX3 uses in this case I2C bootloader with fallback. First the bootloader of I2C is executed and then this bootloader connects through superspeed and on the SS way the final application firmware file will be uploaded through vendor request and then re connects to super speed. 

         

      Thanks
