I was having trouble installing a printer and was advised to delete all USB controllers, being assured they would reinstall when I rebooted, but they didn't!! Now I can't use the mouse etc. I have searched the WEB for hours and have found no answers. I have a Dell Dimension 2400 with XP Home,and SP2 installed later. I believe they are Intel drivers that i need. I have tried the Windows disk, told it to search online etc but it always says "An error occurred .... The driver installation file is missing a necessary entry. This may be because the INF was written for Windows 95 or later'
Any ideas - I'm getting beyond desperate.

New ZealandDo you have any other CD's that came with the computer? I've been working on a 2400 recently and it came with two ResourceCD's that have the necessary drivers. If you don't have the CD's, the majority of the included drivers can be found here...

The Intel driver can be found under Chipset. Is it only USB devices that aren't working? Does a PS2 mouse work alright in that computer? If so, right-click on My Computer, go to Properties, click on the Hardware tab, and click on Device Manager. Anything with missing drivers should be marked with a yellow hazard sign and/or question mark. Try installing the corresponding drivers from the Dell site and post back with any problems or results.Thanks - I found the CD and it has a chipset installation utility which I installed but it didn't help. I then installed the one off the Dell website but still no luck. There was nothing like a USB driver so I hope that was the right file. I also got a bunch of USB drivers from Driverguide but they didn't do it.
I don't have a PS2 mouse but I can navigate into Device Manager with the kb. The USB controllers all have yellow warning signs except the USB2 which I somehow got working along the way.
Just had another look in device manager and I now have a yellow ! under system devices for the Intel SMBus controller. Trying to fix it produces the same error message about INF files. But - I have now managed to get back all the USB controllers, but they don't work, so I guess this Bus Controller is the key. Now where do I get that? I ran a PROGRAM called infinst_autol.exe from Intel but it doesn't seem to do it.

Sally CWell, it looks like we're on the right track...hopefully. Ha. Try this fix from Intel and see if it helps...

I may well be back for more help! CONGRATULATIONS on your fresh install of Windows ! !

Sometimes we avoid it but doesn't everything run so much better ? ?

Yes, you're right and it actually was quite easy. All done in a morning. And it is much faster.A good format and reinstall solves all Windows problems....for a while. Quote
