Universal Serial Bus Port 1:0 Differential: These differential pairs are
used to transmit data/address/command signals for ports 0 and 1. These
ports can be routed to USB UHCI Controller #1 or the USB EHCI
Controller.
NOTE: No external resistors are required on these signals. The ICH4
Universal Serial Bus Port 3:2 Differential: These differential pairs are
used to transmit data/address/command signals for ports 2 and 3. These
ports can be routed to USB UHCI Controller #2 or the USB EHCI
Controller.
NOTE: No external resistors are required on these signals. The ICH4
Universal Serial Bus Port 5:4 Differential: These differential pairs are
used to transmit data/address/command signals for ports 4 and 5. These
ports can be routed to USB UHCI Controller #3 or the USB EHCI
Controller.
NOTE: No external resistors are required on these signals. The ICH4
Overcurrent Indicators: These signals set corresponding bits in the USB
controllers to indicate that an overcurrent condition has occurred.
USB Resistor Bias: Analog connection point for an external resistor to
ground. USBRBIAS should be connected to USBRBIAS# as close to the
resistor as possible.
USB Resistor Bias Complement: Analog connection point for an
external resistor to ground. USBRBIAS# should be connected to
USBRBIAS as close to the resistor as possible.
