ICH7R USB Controller Overview
Up to eight high-speed, full-speed or low-speed USB devices are supported by the ICH7R
on the PCIE-9452. High-speed USB 2.0, with data transfers of up to 480MB/s, is enabled
with the ICH7R integrated Enhanced Host Controller Interface (EHCI) compliant host
controller. USB full-speed and low-speed signaling is supported by the ICH7R integrated
Universal Host Controller Interface (UHCI) controllers.
2.6.8.2 PCIE-9452 USB Implementation
Only four of the Intel® ICH7R USB ports are implemented on the PCIE-9452. Two ports
are connected to two external connectors and two ports are connected to an 8-pin
onboard header. See Figure 2-6 .

2.6.8.3 Backplane USB Implementation
The remaining four Intel® ICH7R USB ports are interfaced to the backplane through a
golden finger on the bottom of the CPU card. See Figure 2-7 . These four remaining USB
ports can be implemented through connectors on the backplane.
