Recently I have just started a project , in which I need to interface a device ( a complete circuit board of 8052 series micro controller) with USB port ( because current board design allows only serial port communication, but I need to upgrade it to usb).
So please any help regarding usb interfacing ( or just basic interfacing ) is very much welcome.
ps: I am a novice. So try to write in easy-to-understand language 
thanx in advance.
regards
