Default USB 2.0

The content incorporate USB 2.0 32-bit support for EHCI Host Controllers on the Microsoft(r) Windows(r) XP operating system (build 2600). Please note that Windows .NET Server and Windows XP SP1a will NOT need this package, because they already contain software support for USB 2.0.

USB 2.0 EHCI Host Controllers Supported

The drivers provided have been tested with the NEC USB 2.0 host controller and the Intel EHCI Host Controller. The hardware IDs of the USB 2.0 host controllers supported by the provided solution are as follows:


The driver will not install on any other EHCI controllers with hardware IDs different from the ones stated above. Microsoft’s plans regarding support of additional EHCI controllers can be found on [url]***********[/url]

USB 2.0 Hub support

USB 2.0 hubs are supported natively by Windows XP. All hubs that report correct hub class code in their device descriptor will be compatible with the existing USBHUB.SYS driver in Windows XP.

Both packages below need to be installed to support USB 2.0 on windows XP.

The USB EHCI package contains the Enhanced Host Controller mini-port driver. The INF file is responsible for loading the USBEHCI.SYS host controller miniport on a Windows XP system, and the host controller coinstaller (HCCOIN.DLL) is responsible for synchronizing communication between the Enhanced Host Controller and the companion host controllers.

QFE fix for existing USB driver stack on Windows XP

The QFE package is responsible for updating USBPORT.SYS and USBHUB.SYS on Windows XP. Localized versions of this package only differ in terms of the QFE installation user interface (UI), displayed during package installation. Since this package replaces USBPORT.SYS and USBHUB.SYS with updated versions, a reboot is essential.

Installation Directions

Please follow these directions for a smooth installation of the USB 2.0 package.

Both the USB EHCI package and the QFE (described in section 2) must be installed.
Always install the QFE package first. This will prompt for a reboot. Before you reboot, please ensure that you have installed the EHCI Package also. Install the USB 2.0 EHCI package using Plug and Play INF driver installation procedures.
Reboot your machine.
