          Hello,

           

          Can you please double click on the device in the device manager and send me a screen shot of the Device Status under General Tab.

          Please the see the below image for reference.

           

          I was able to get the device enumerated using the .hex file in the application note.

          Can you please let me know if you are loading the .hex fiel to RAM or the .iic file to EEPROM?

          You can also try to update the driver manually by right clicking on the device and select Update Driver -> Select automatically for updated driver software

           

          Thanks,

          Yatheesh
