To start, I have an Arduino UNO clone made by GEEKCREIT.
I am not the Original purchaser. I acquired this UNO in a box of "Stuff" that I bought at a local "HAM Fest" and am trying to get it to work.
I have spent the last week reading and trying everything I can find here and elsewhere with absolutely no luck.
This board DOES NOT have the CH340 serial interface IC.
It has the Atmel Atmega16U2 interface.
The problem seems to be that the Atmega16U2 has the Incorrect PID. The VID seems to be correct.
When connected to a Windows 7 or Windows 10 machine, the Device manager shows the Uno as a libusbK USB Device / AVRISP mkII with a USB\VID 03EB and PID 2104.
When connected to a Linux machine, lsusb shows it as 03eb:2104 Atmel Corp. AVR ISP mkII.
The Atmega16U2 will NOT go into the DFU mode and will not program through its ICSP header.
Can someone point me it the right direction of a fix or solution to getting this UNO Atmega16U2 back to a working bootloader????
Or is this just a LOST cause.
I believe that someone prior to me getting this UNO may have converted it to a AVRISP MkII.
This the message I get When using another UNO as ISP trying to burn the HoodLoader2 16U2 bootloader to the "Broken" UNO Atmega16U2.

avrdude done. Thank you.
