How to communicate AT89S52 with PC via USB port

[Manu]

I have to connect AT89S52 to PC via USB port for which I am using FT232R (USB to UART interface IC) for this purpose. I have to transfer data from PC and it is stored in external memory connected to AT89S52 and vice versa for which a software is installed in PC. So I want to know what are the steps involved and protocols used to communicate with PC in this case. Thank you.

Hi Ganesh,

Which is the external memory device that you want to use?
