virtual usb 16f628

Yes. But why bother? Generic convertor chips are cheap. Besides, writing the virtual serial port driver for your own convertor is no trivial task.

Added : On 2nd thought, the 16F628 may not even have enough IO pins to interface any USB device controller IC.

16f628 pl2303

Try USB-RS232 converter from FTDI company.

Or, try to use this ucontroller frm microchip: PIC18F4550
"... the availability of three serial ports: FS-USB(12Mbit/s), I²C™ and SPI™ (up to 10 Mbit/s) and an asynchronous (LIN capable) serial port (EUSART)"

Ow..I never thought it's complicated as that..
I was considering PL2303 since FTDI is not available in my place..
but the PL chip has a bad impression in me..I bought a USB data cable for my Nokia phone and it was not working the chip inside is PL2303, so I think PL chips are not that good..

the less difficult thing is to buy a dedicated chip and use virtual port driver...
