USB conflict in Win98 SE

[tdhart]

After having some intermittent booting problems with Win95 showing write protection error. I formatted the hard drive and installed Win98SE, and that fixed that problem, but in the System icon under device manager there is a conflict with the USB. It shows a SIS 7001 PCI to USB Open Host Controller which has no conflict, and the USB Root Hub shows a conflict.
Does anyone know how to fix this? Microsoft has no file or patch for this one.

Hi tdhart

My guess is that it needs an updated driver, probably available from the SiS website.

Another possiblility is that you might need to free up an IRQ for the USB to use. (Or juggle IRQs, anyway, until all your devices are happy campers)

Do you see a message in Device Manager telling you what resource is in conflict? (such as a memory address or IRQ)

I've been kinda crazy busy these days, but I'll check back again tomorrow . . . If you haven't a solution by then, I'll look around a bit & see what I can find . . .

The only thing I could get on SIS website is updated IDE controller drivers which I did. The IRQ are as follows:
03 IRQ Holder for PCI steering
03 SIS 7001 PCI to USB Open Host Controller

09 IRQ Holder for PCI steering
09 USR Modem 56K

11 IRQ Holder for PCI steering
11 S3 Virge PCI 325

14 Sis IDE Controller
15 Sis IDE Controller

Thats the main ones I think you need. Is there anything not right about those?

Hi again

Well, I poked around a little, and it looks like the USB Root Hub driver is usually written by Microsoft, and is probably provided with the Win98SE disk (in fact, the same goes for the SiS 7001 part: it's written by Microsoft too).

If you are seeing a little yellow exclamation point next to the USB Root Hub in Device Manager, try clicking on it to select it, and then click on "Properties". Device Manager should have some text there that explains what it feels is the conflict/problem.

If you haven't looked at your motherboard's BIOS settings in a while, you might want to go in there and make sure that the USB settings are Enabled where necessary. Your motherboard's manual (if available) can help you with that. If you don't have a manual, they are fairly easy to find online.

You can also try removing the hub in Device Manager, and letting Windows re-detect and re-install it on reboot (have your Win98SE disk handy, it might ask for it)

If this doesn't get your going, post again & we'll do more looking around.

Hi Gary,
Yes thats the problem with the yellow exclamation on USB Root Hub. Tried removing and reinstalling but get the same device on plug n play. I have tried removing the SIS USB and installing the Standard HCI Controller and Root Hub which takes the exclamation point away, but when I reboot the conflict on Root Hub comes back?

[tdhart]

As far as the message goes it doesnt give an error number, but just says....due to transfer request failures, a hub has been disabled. Check your cables and restart.
But when I was using Win95 there were no conflicts with USB.

Hi again

After checking a few articles over at the Microsoft site, I'm hoping that we can get you an easy fix with a Bios setting...

Enter your PC's Bios Setup screens (usually by pressing F1 or the Delete key when rebooting). Look for a menu that has the item "Assign IRQ for USB". The value will be either Yes or No . . . or perhaps Enable or Disable. The value needs to be either Yes or Enabled.

If that's not it . . . Well, we can keep trying. Seems like there are a lot of issues with USB and Win98.

Do you have a USB device attached to the system? See if you can test it. . . . Does it work at all?

If you want to check out Microsoft's "General USB Troubleshooting" article, it's Q263218 over in the Knowledge Base section of the MS support site.

I'll be able to check back a little sooner in the morning . . . I'll be at work (and the computers don't have any diapers to change or school lessons to complete or gymnastics lessons to go to).....

One more post before bedtime

After looking again at your IRQs list, it seems odd to me that the SiS USB controller is on IRQ3...that's usually in use by a COM port.

Do you have the devices set to "Use automatic settings" in the "Resources" tab in Device Manager?

Also, some of the old S3 cards used resources that they wouldn't report to Windows. You could try a newer driver (especially if you're still using the Win95 one) or perhaps move it to a different PCI slot.

And remember, that with a yellow exclamation mark in Device Manager, things often continue to work just fine . . . they just aren't configured the way Device Manager expects them to be.
Good Night . . .

Thanks for your help Gary, but Im just gonna leave well enough alone. Its not messing up anything right now, so I will live with it.

I downloaded the driver at S3 website, but it didnt help. The bios doesnt have anything regarding USB. I switched to the Manual config. for all IRQ settings and they all show PCI/ISA Plug n Play except for 7 and 14 and 15 which is Legacy.
The PC is a custom, and kinda old its a 200 mhz, w/Gigabyte MB.
It was originally installed w/Win95, but has no USB ports.

Again, thanks for your help. That conflict was bugging me, but I can live with it.

[GaryRouth]

If you don't have the USB cable running from the motherboard to a panel on your case, you can disable USB altogether. (It'll free up an IRQ, if you ever need it) You probably could get it to work eventually, but it might take a lot of moving things around (trying the video, audio, modem in different slots ...re-installing drivers, etc...)

Sorry if I was confusing, but actually I had meant that I recommend having the Device Manager settings on "automatic settings". The Bios setting can be automatic, too, or manual... in that case, it's not a huge deal either way (things are a little more flexible if you choose automatic)

If you're bored someday & want to add a USB device, just to see if it can be done on your setup...visit the Gigabyte website and see if a mainboard bios update might have fixed USB issues. . .

I've got to get another cup of coffee. Got to re-group after a defeat at the hands of that little yellow exclamation mark!

it nice to see that someone made this thread...

I have the exact same problem in win98

the "SIS 7001 PCI to USB Open Host Controller" is fine but the "USB Root Hub" has a conflict with it...

The NTKERN.VXD device loader(s) for this device could not load the device driver

Anything i can do to solve this?
I need the USB port for my MiniDisc Player...
