Finalizing USB 2.0 Hi-Speed hardware settings USB 2.0 Hi-Speed PCI cards that use an NEC chipset have 3 USB host controller engines on board. Two of the host controller engines handle USB 1.1 transactions. One of the host controller engines handles. USB 2.0 transactions. USB data traffic is automatically routed to the proper host controller engine depending on the speed of the device that is plugged into the USB port. This essentially creates 3 concurrent USB buses. These USB buses allow devices to run in a less congested traffic environment. This helps devices such as color printers, scanners, video cameras and mass storage devices, which require a high bandwidth, to work well together. The NEC PCI to USB Enhanced Host Controller driver handles USB 2.0 Hi-Speed (480 Mbits/s) Traffic . The two NEC PCI to USB Open Host Controllers handle Full-Speed (12 Mb/s) and LowSpeed (1.5 Mb/s) traffic.
