I'm still having a problem. I installed Service Pack 4 but Windows 2000 still does not see an external drive that is plugged into my IOGEAR USB 2.0 Enhanced Host Controller Card. I also have USB 1 on my system, connected to a USB hub, and the drive can be seen that way.
I was told that Windows 2000 originally did not include support for EHCI host controllers, so I updated with SP4, thinking that would resolve the problem, but the external drive is still not seen on the USB 2 port. Device Manager shows that it is installed with the correct driver, and I even tried reinstalling the driver. It does not show an exclamation point in a yellow circle with status code 28. Everything looks fine, and it does recognize things like my digital camera and my mp3 player.
So I found this website with a "workaround" on it:
I do NOT experience any of the symptoms listed:
• 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.
The workaround (shown below) says to click the "Windows Update Catalog" at
so I went there and found "Windows Catalog" (without the word "Update"). The workaround then says to click on the "Find driver updates for hardware devices". But I can't find anything that says that so I can't complete steps 3 thorugh 8.
WORKAROUND
To install USB 2.0 support in Windows 2000, follow these steps:
1. Visit the following Microsoft Windows Update Web site:
2. Click Windows Update Catalog. If Windows Update Catalog does not appear, click the following Microsoft Knowledge Base article, and then follow the instructions to add it:
235263 WINUP: How to Use the Personalize Button on the Windows Update Site
3. Click Find driver updates for hardware devices.
4. Click Other hardware.
5. In the Manufacturer name box, click Microsoft Corporation.
6. In the Operating System box, click Windows 2000 Professional RTM.
7. Click Search.
8. Download the driver that is named "NEC usb software update released on June 01 2001."
Also at the bottom of the page it does say the following
APPLIES TO
• Microsoft Windows 2000 Professional Edition
Is it possible that if I don't have Windows 2000 Pro that I can't use USB 2.0 for external disk drives? I find that hard to believe!
Any help would be appreciated,
