Answer 2

The term "USB port" means nothing. B on USB means "bus", this is a common way for any device to talk to the machine. A driver is required to use the device. Just as you have drivers for your video card and your network card.

The usual way to force a USB device to use user mode code is to use a driver to emulate an old-fashioned serial port. You would use the SerialPort class in .NET. Check your device’s specifications to see what its driver does.
