Finalizing USB 2.0 Hi-Speed hardware settings
OrangeUSB 2.0 Hi-Speed products 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 controllers engines handle, 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 OrangeUSB 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 OrangeUSB USB 2.0 Host Controller driver handles USB 2.0 Hi-Speed (480 Mbits/s) traffic. The two NEC USB Open
Host Controllers handle Full-Speed (12 Mb/s) and Low-Speed (1.5 Mb/s) traffic.
Check your Windows System/Device Manager to confirm proper installation of USB 2.0 Hi-Speed drivers:
Right click on the “My Computer” icon. Select
Properties
from the pop up menu, click on the “Hardware” tab then click on
the Device Manager button. Scroll down to the “Universal Serial Bus controllers” category and click on the plus sign next to
it. There may be additional devices in the list being displayed, but all of the below devices should appear.
An X through a device’s icon means the device as been disabled. A circled exclamation point through the device’s icon
means the device has a problem. The type of problem will appear in the
Properties
dialog box for the device. To view the
Properties dialog box for a device, double click on it.
If the Windows XP Device Manager “Universal Serial Bus controllers” category does not look the same as it does below,
Windows XP may have installed the Microsoft NEC PCI to USB Enhanced Host Controller instead of the OrangeUSB USB
2.0 Host Controller. This will work fine as long as the NEC PCI to USB Enhanced Host Controller (Driver Date 6/1/2002) is
from Windows XP Service Pack 1.
NOTES:
To verify the NEC PCI to USB Enhanced Host Controller driver date, double click on it. Select
the Driver tab. The NEC PCI to USB Enhanced Host Controller driver date must be 6/1/2002 or
newer.
If you wish to use the OrangeUSB USB 2.0 drivers instead of the Microsoft USB 2.0 driver, double click on the “NEC PCI to
USB Enhanced Host Controller” driver. Click on the Driver tab, then the Update Driver button. Go back to Step 5 in the
Installing OrangeUSB 2.0 Hi-Speed Driver in Windows XP section and follow the instructions through Step 12.
