I have an Arduino R1 board (the very first one) and I managed to solder the resistor into Arduino's Atmega8u2 (I went to a specialist in order to do that). Then I reset atmega8u2 and by wiring the pins mentioned in: https://www.arduino.cc/en/Hacking/DFUProgramming8U2
I can confirm it via this message over my GNU/Linux machine by running
[ 1544.679504] usb 1-6: new full-speed USB device number 42 using xhci_hcd [ 1544.808341] usb 1-6: New USB device found, idVendor=03eb, idProduct=2ff7 [ 1544.808350] usb 1-6: New USB device strings: Mfr=0, Product=1, SerialNumber=0 [ 1544.808356] usb 1-6: Product: Arduino Uno DFU
I also to confirm that I run
lsusb and I got the following result:

Further indicating to me that arduino is in DFU mode over my ubuntu 16.04 machine. Also I further verify via
dfu-util -l command:

The I try to run:
sudo dfu-programmer atmega8u2 erase
But for some reason I get the following error:
dfu-programmer: no device present.
Do you know why I get this error and how I can fix it?
I installed the latest version of dfu-programmer and compiled from source via https://sourceforge.net/projects/dfu-programmer/files/dfu-programmer/0.7.2/ but still I get the error. I also tried to compile it with
I also tried this version with
libusb-1.0.0 but still the same error occurs.
As many suggest I tried to do multiple times but still I get this error.
I also used
dfu-util and I try to insert the data into the atmega8u2 via:
sudo dfu-util -d 03eb:2ff7 -D ./Arduino-usbserial-uno.hex -R
But I get the error:
