In my experience, just download the C18 compiler (free as is MPLAB
IDE) from Microchip. Target a PIC with USB (18F4550 etc). Download
Mchip's USB demo which connects to Hyperterm via a RS232 serial
emulation. The driver installed on the PC, is also available from
Mchip. This setup makes the USB PIC appear to the PC as a standard
COM port. Then just select that COM port with Stampplot and your good
to go.

All the best on your project,
