Yes, it is. It's cool how easy you can port your applications to USB...
I think you need to remember what you're actually doing!, this isn't 'porting your application to USB' - it's leaving your application with a serial interface, and merely adding a USB to Serial converter. You can buy these at low cost as an external unit, and even as part of a connecting lead - which is no different to using these converter chips.
If you want to port your application to USB, you need to use one of the USB enabled PIC's - and learn the complexities of USB programming!.
