USB Root Driver Problems

[fasgadh]

Hi
Windows 98SE Computer

I'm trying to install a Opti 82C861 USB driver
The Opti 82C861 PCI to USB Open Host Controller loads ok
But in Device Manager the ROOT HUB is showing a problem as follows
The NTKERN VXD device loader for this device could not load from the device

I tried to update this driver from the 98 SE cd but then get a fatal exception at VXD NTKERN

Ive deleted the USB device and started again many time but always with the same outcome

I would be grateful for any help

According to Opti support, you can either move the card to another slot, or try adding some files manually using the procedure I've copied-and-pasted below:

Ntkern.vxd Error

Q: In Windows 98se, after Installing the USB card, I get the following message in the Device Status: "Ntkern.vxd cannot load the driver. Pls. update driver." or there is an exclamation point or a question mark on the 82C861 USB controller in the Device Manager.

A: Shutdown the computer and reinstall the USB card in a different PCI slot. Restart your system then follow the installation procedure for Windows 98se. If this does not work, try the instructions below.

You need to copy four files from the Win98SE CD to the following directory in your system. (Note: Easiest way to look for these files in the 98 CD is to right click on START and do a Find.)

openhci.sys to c:\windows\system32\drivers
Ntkern.vxd to c:\windows\system
usbhub.sys to c:\windows\system32\drivers
usbd.sys to c:\windows\system32\drivers
Before you copy these files to your system, make sure that you take out the USB card from the PCI slot. Then:

Copy the files to the designated directories
Shut down your system
Install the USB card in a different PCI slot
Turn on your system (make sure that your 98SE CD is still in the CD-Rom drive). When the system boots up, it will detect the device and will ask you where to look for drivers.
Select 'Search for the best driver for your device'
Click on 'Specify Location'
Type in c:
Click on 'Next'
Click on 'Finish'

Thanks for your reply Gary,
Ive sorted it out know unfortunately I didnt give you as much information as I should have done because it turns out that the USB card was not compatable with the low spec PC in which it was inserted (500mhz) I didnt think this would have any bearing on it ( what a fool) anyway on obtaining a compatable USB2 card everything works fine .

Thanks for your help
