I am new to implement USB on AVR. I want to make a simple USB to Serial convertor with atmega8 which creates a virtual com port like USB Doper.
Can somebody please help me with this? I just want an idea/schematic/code if possible.
USB to Serial
Please look at Osamu Tamura's avrcdc: http://www.recursion.jp/avrcdc/. I think this is exactly what you want.
