The BNC connector J14 (D-) is in parallel with the D- line of the
J2 USB connector. The BNC connector J15 (D+) is in parallel
with the D+ line of the J2 USB connector. If you want to use the
J14 and J15 BNC connectors, you must populate R
with 0Ω resistors. These BNC connectors can be used to
connect test equipment to evaluate the performance of the IC.
