SYMPTOMS
You may experience any of the following symptoms:
 * Your Hi-Speed Universal Serial Bus (USB) 2.0 device does not operate in Hi-Speed mode.
 * An Enhanced Host Controller Interface-compliant (EHCI-compliant) USB host controller appears in Device Manager with an exclamation point in a yellow circle, or with status code 28.



CAUSE
This problem occurs because Windows 2000 does not include support for EHCI host controllers.

WORKAROUND
To install USB 2.0 support in Windows 2000, follow these steps:  Visit the following Web site:

http://v4.windowsupdate.microsoft.com/catalog/en/default.asp

 Click Windows Update Catalog. Click Find driver updates for hardware devices. Click Other hardware. In the Manufacturer name box, click Microsoft Corporation. In the Operating System box, click Windows 2000 Professional RTM.</li> Click Search.</li> Download the driver that is named &quot;NEC usb software update released on June 01 2001.&quot;</li></ol>

Note The size of the Windows 2000 version of this driver is 107 KB. The Microsoft Windows XP version of this driver is 290 KB.

The files in this update include:

<pre class="fixed_text">   Date          Time    Version         Size      File name 23-Apr-2002  22:46   5.0.2195.5652   135,920   Usbport.sys 18-Apr-2002  23:46   5.0.2195.5605    49,392   Usbhub20.sys 23-Apr-2002  22:46   5.0.2195.5652    19,216   Usbehci.sys 07-May-2002  16:52                     7,159   Usb2.inf 09-May-2002  23:12                     8,736   Usb2.cat 18-Apr-2002  23:46   5.0.2195.5605     6,416   Hccoin.dll

After you install this driver and restart your computer, the USB 2.0 controller and device are listed correctly in Device Manager. If you do not install this update, the USB 2.0 device is listed and functions, but the device does not work at full USB 2.0 speed.
