One thing to keep in mind is that there are devics that act like
a USB device when hooked to USB and act like RS232 when hooked to
a serial port - thus needing nothing more than a cheap adapter
or adabter cable that acts as a "USB to serial converter." This
scheme is quite common on mice and keyboards. In industrial
controllers, you sometimse see a USB port that becomes I2C when
connected to another I2C. These "USB to serial converters" will
*not* work with a USB that is not programmed to imitate another
kind of connection.
