[AVR] ATMEGA8 based USB UART converter

[robert_tru]

I have been designing atmega 8 based usb to uart conversion using v usb and avr cdc 232. The whole circuit seems ok but its not detected in by the computer. It just says USB device not recognized.
Here's the description of the project( https://shortedwire.blogspot.com/2014/09/cheap-usb-based-uart-and-modbus.html ).Any help please I used the code available in AVR cdc.

I have checked and tried to install it though my device is not properly detected. In both 32 and 64 bit system , while installing the driver it says driver not meant for 32 bit system for 63 bit system. http://shortedwire.blogspot.com/2014/09/cheap-usb-based-uart-and-modbus.html
