Orange USB for Windows
General Information about USB 2.0 Technology
you insert the OrangeUSB CardBus card into your PC Card
slot, Windows should detect the card and attempt to install
the proper software drivers. If this does not happen, check
the following items:
you have tried all suggestions below and still have no
success, the card may not be compatible with your system.

In the Windows Device Manager the "NEC PCI to USB Open Host
Controller" shows up with a yellow exclamation mark. Under
the Device status section, the message "This device cannot
start. (Code 10)" appears. How can I correct this?
the System BIOS configuration Utility to change the "Assign
IRQ for USB" from Disabled to Enabled. This usually occurs
if the system does not have built-in USB.
Micro has no plans to develop and support Linux drivers for
the OrangeUSB products. However, we will publish links to
known Linux web sites that have drivers that support the
OrangeUSB products under Linux.

support for Linux.
2.0 is an evolution of the USB standard. USB 2.0 handles up
to 480 Mbps that creates opportunities for a new class of
high performance outside-the-box peripherals. USB 2.0
provides a straightforward performance enhancement to USB
1.1 and offers forward and backward compatibility with USB
1.1 devices. USB 2.0 preserves USB 1.1 in the plug and play
model, driver auto installation, and power management
features. With use of the same cables and connectors, USB
2.0 is fully backward compatible with USB 1.1. For developer’s,
no changes are required for applications and device drivers.
USB 2.0 offers a compelling opportunity to migrate their USB
peripherals to higher performance into the huge installed
base of USB-capable PCs.
2.0 offers 480Mbps of bandwidth, which are 40 times more
bandwidth over USB 1.1 of 12Mbps for Full Speed devices or
1.5Mbps for Low Speed devices. High performance devices such
as mass storage, broadband network connection, color printer
and scanner can now be practically implemented in USB 2.0
for required bandwidth. Especially for printer and scanner
type of application can take advantage of delivering data
right on the time of demand which reduces the need of memory
buffer inside the specific applications. Unlike in USB 1.1
and other buses, low and full speed devices will run at high
speed rate of USB 2.0. This allows other devices on the bus
to share the bus.
OrangeUSB 2.0 Hi-Speed board will operate out of the box as
a fully compliant USB 1.1 host controller under Windows 98,
Windows 98 Second Edition, Windows 2000 and Windows Me. Once
are installed, users can connect USB 1.1 and USB 2.0
Hi-Speed peripherals to a USB 2.0 Hi-Speed port and get a
data transfer rate of up to 480 Mbits/s (Hi-Speed). Current
USB 1.1 peripherals will continue to have a data transfer
rate of 12Mb/s (Full-Speed) and 1.5Mb/s (Low-Speed).
the initial shipment of the "USB 2.0 Ready" OrangeUSB
product, the final version of the OrangeUSB host controller
drivers were not complete. OrangeUSB 2.0 Hi-Speed Drivers
are now available on our software
Check back periodically for updates to these drivers. The
OrangeUSB 2.0 Hi-Speed Drivers support Windows 98 SE,
Windows Me, Windows 2000 and Windows XP.
98SE, Windows Me, Windows 2000 and Windows XP is supported
Windows NT, Windows 95 do not have native support USB.
Therefore will not be supported under USB 2.0.
USB 2.0 is forward and backward compatible with USB 1.1. All
USB 1.1 devices can be used interchangeably with USB 2.0
devices without affecting performance of either.
USB 2.0 is backward compatible with USB 1.1. You can use the
USB 1.1 host controller with USB 2.0 devices. But you will
not enjoy the 480Mbps benefit of the USB 2.0.
USB 2.0 is backward compatible with USB 1.1 even down to
cable and connectors. All cables and connectors in USB 2.0
and USB 1.1 are created equal. You can use the existing
certified USB 1.1 cables to enjoy the full benefit of USB
USB 1.1 devices will not run at 480Mbps in USB 2.0
environment. But USB 1.1 devices will maintain better
performance running through the OrangeUSB. This is due to
brilliant architecture of multiple host controllers inside
the OrangeUSB host controller chip. Users will be more
productive with multiple USB 1.1 devices running together
thru the OrangeUSB board.
OrangeUSB 2.0 Hi-Speed PCI board uses an NEC chipset that
has 3 USB host controller engines on board. Two of the host
controller engines handle USB 1.1 transactions. One of the
host controller engines handle, USB 2.0 transactions.
OrangeUSB hub has 4 downstream ports allowing multiple USB
devices to be connected upstream into an USB PC host. When
USB 1.1 devices are plugged into the hub, the transaction
translator inside the hub controller board translates all
transactions from 12Mbps in Full Speed or 1.5Mbps in Low
Speed into 480Mbps Hi-Speed domain. Essentially all traffic
between hub and PC host will only be communicated in
480Mbps. This translation allows 480Mbps of USB 2.0 to be
