I had a perfectly working Arduino Uno and I needed to try out a project that required USB host on the Arduino so that it could send keyboard commands to my Windows PC.
I followed(this) guide to try and replace the firmware on the atmega chip with the one on the guide. I managed to do it successfully but the uno just shows up as a USB Input device in device manager. There is no com port and I cannot upload any sketched to the Arduino. The board just lights up and the Arduino IDE doesn’t recognise the board.
I am experienced with the Arduino but, this is my first time trying to flash any of the chips.
These are my specs:
Windows 10 with the latest Arduino software
Arduino Uno Compartible board with the ATMEGA16U2 chip (which I tried to flash)
I have included some pictures of the device manager and the Arduino IDE if it would help.
Any help would be appreciated ,
