I have installed the nusb31f mass storage driver on my son's Windows 98 SE computer but whenever he tries to plug in his MP3 player, it gets detected, the drivers installs but can't initialize, apparenly because NTKERN.VXD loader as unable to load the driver. (Something close to that anyway, translated to the best of my ability as it's a french language Windows.)

Any ideas what could be wrong and how to fix it?

Where are you reading the error from? Do you get a window opening when the MP3 player is connected, or are you looking in device manager?

If you can give the exact error message as you read it (in French) it may help. My French is extremely poor, but still it may help!

When looking at the device manager, a new device appears when then player is plugged in, called "Périphérique de stockage de masse USB" (USB Mass Storage Device) with a yellow exclamation mark against it.

When looking at the properties, the following status is indicated: "Le ou les chargeurs de périphérique NTKERN.VXD de ce périphérique n'ont pas pu charger le pilote du périphérique. (Code 2.)", wich is then followed by the driver update button.

I believe the correct translation is "The Ntkern.vxd device loader(s) for this device could not load the device driver. (Code 2)"

Try doing the following:
Arrow Browse to c:\windows\system32\drivers in Windows Explorer
Arrow Find the following files and rename them so you change their file extensions from .sys to .old
• Uhcd.sys
• Usbhub.sys
• Usbd.sys
Arrow Insert the Microsoft Windows 98 CD-ROM into the drive
Arrow Click Start, and then click Run
Arrow Type sfc, and then click OK
Arrow In the System File Checker window, click Extract one file from the installation disk
Arrow In the Specify the system file you would like to restore box, type uhcd.sys, and then click Start
Arrow In the Restore From box, type X:\Win98 changing X for the letter of your CD drive
Arrow In the Save file in box, type c:\windows\system32\drivers
Arrow Click OK, and then click OK again
Arrow When Windows finishes restoring the file, click OK
Arrow Repeat the previous 6 steps to restore Usbhub.sys and Usbd.sys. When you finish restoring the files, click Close
Arrow Restart the computer, and try inserting the MP3 player again

I tried renaming the files and extracting the ones from the Windows 98 CD, then rebooting. Unfortunately I get the same behavior as before.

OK, looks like the MP3 player isn't compatible with the drivers. What make is is?

One more thing you can try is using the System File Checker again to extract NTKERN.VXD to C:\WINDOWS\SYSTEM and C:\WINDOWS\SYSTEM\VMM32

You will not be able to rename the file before doing this.

The MP3 player is some generic Hong-Kong made player I got off eBay. I also tried an old 32mb Kingston memory key and I get the same result.

I also tried replacing the NTKERN.VXD in both the SYSTEM and VMM32 directories but it didn't help.

I'm not sure what more to suggest. It could be that there is a problem with the windows installation. Short of reinstalling Windows, I'm out of ideas.

Do any other USB devices work? Printer etc.
