a USB current monitor on the Carrier Board may drive this
line low. Do not pull this line high on the Carrier Board.
B38 USB_4_5_OC# I 3.3V CMOS USB over-current sense, USB ports 4 and 5. A pull-up for this
line shall be present on the module. An open drain driver from
a USB current monitor on the Carrier Board may drive this
line low. Do not pull this line high on the Carrier Board.
A38 USB_6_7_OC# I 3.3V CMOS USB over-current sense, USB ports 6 and 7. A pull-up for this
line shall be present on the module. An open drain driver from
a USB current monitor on the Carrier Board may drive this
line low. Do not pull this line high on the Carrier Board.

Table 3-7: USB Signal Description
3.4.2 USB Keyed Connector Protocol
To minimize end user termination problems, USB uses a “keyed connector” protocol. The
physical difference in the Series “A” and “B” connectors insures proper end user
connectivity. The “A” connector is the principle means of connecting USB devices directly
to a host or to the downstream port of a hub. All USB devices must have the standard
Series “A” connector specified in this chapter. The “B” connector allows device vendors to
provide a standard detachable cable. This facilitates end user cable replacement.
