USB is nearly useless for NTP!  USB has latencies sufficiently large 
and variable to render it unsuitable for use with NTP.  Most computers 
used to be sold with one or more serial ports.  The newest computers may 
not have serial ports as they come from the factory but there is no 
reason why one or more serial ports can't be added.
