This is the USB Type B connector to connect to the computer.
This allows the user to either: (1) connect jumpers horizontally to the top and bottom pin
pairs to connect to the on-board MMBT3904 or (2) to remove the jumpers and connect a
remote diode directly to the input of the LMxx.
TCRIT# and ALERT# are the open drain LMxx output pins
SMBus Clock and Data signals are available to the user for system monitoring.
