// Filename: usbi.h

// Project: XuLA2 board
//
// Purpose: This package attempts to convet a JTAG over USB based
// communication system into something similar to a serial port
// based communication system. Some differences include the fact that,
// if the USB port isn't polled, nothing comes out of the port. Hence,
// on connecting (or polling for the first time) ... there might be a
// bunch of stuff to (initially) ignore.
