Refreshing Arduino Driver IC ATmega16U2 by DFU Mode and Flip Atmel Software

Hi here is one new topic about troubleshooting of Arduino USB Port error during program downloading. 

When we download Arduino IDE sketch into Arduino then code compile but apear an ERROR during downloading or some time hang. This is an error of ATmega16U2 USB serial port driver IC. Just reprogram this IC as following.  

Requirement:

1. Atmel Flip Software

Click image for downloading

by using this software we will access ATmega16U2 and reprogram.

Step 1: Connect Arduino UNO R3 board to PC/Laptop

Step 2: Open Flip Software

Step 3: Enter Arduino board into DFU mode (Device Firmware Update) 

Step 4: Open USB serial Port in Flip as

 

Step 5: Select device (USB driver IC ATmega16U2)

Step 6: Load Hex file for mega16U2

use this link for this file:

file:///C:/Program%20Files%20(x86)/Arduino/hardware/arduino/avr/firmwares/atmegaxxu2/

this file is already in your C drive.

Step 7: After loading Hex file then RUN it for Downloading in ATmega16U2

Step 8: At last disconnect Arduino board then reconnect. Your Arduino is OK now.

Plz Comment any issue
