Vista wont recognise any usb device hotfix kb940199

Hey There,

I could really do with some help, every USB device I plug in will not work,
when i plug something in like my mouse for instance it does come up with new hardware found but cannot locate or install drivers, I have the instalation disk with the drivers and these ARE installed, also it was fine before, when I first purchased my mouse logitech MX Air I simply plugged it in and it recognised it and installed the drivers did'nt even need 3rd party software now it says "unknown device" and cannot find the drivers either from the disk or windows update, it is like this on every device even on simple things like usb hubs and memory sticks, it recomends that I download Hotfix KB940199 as this may resolve the problem but i get an error message pop up everytime saying this does not apply to your system (it is the x64 hotfix) argggh how frustrating PLEASE PLEASE PLEASE HELP I cant use half the equiptment I have because of this problem,

Many thanks

Rickie

go into device manager and select usb and disable each one then enable them again this has fixed my not recognized usb devices in the past

Hi there,

Thanks for your reply but i have tried this and still will not work, in device manager unistalled every usb device shut down pc, cleared CMOS, restarted pc plugged in USB device and exact same thing get a message saying windows cannot install usb device although it has done in the past, also have tried pointing it to search for drivers in window32 ??

Hello rickieh2008: Sorry your having trouble.

Try reinstalling your chipset driver. You can find it either at your computer manufacture website or the companys website that built your motherboard. Offten that can force the USB drivers to reinstall and begin working.

If not...

Have you installed anything new into your system lately. This could be a long shot but prehaps you have a conflict.

Please post back with your system specs this could help others help you.

Good luck.

I have just descoverd a page that is talking about this exact same problem and it seems it is not just limited to me, by the looks of it scrolling around various websites hundreds of people are affected,

It seems to be Microsoft's fault (great job guys) and is caused by a recent security update which was released last week. (link below)
USB Devices Killed By Vista UpdateOf course in true microsoft fashion you cannot uninstall this update so will have to roll back my system and set updates to manual untill a fix is released, will let you know how it goes but dont see any reason why this would'nt work, Its just really frustrating shouldent have to go through this because of there cock ups agggh

Fingers Crossed

Kind Regards

Rick

only disable one at a time not all together then plug in a usb device

Hiya Rick

I was just going to point you to a "MS Update Kills USB Devices" page, but looks like you found one already.
Many WUpdates can be rolled back if problems arise, but this seems to be from a Windows Defender Update and that's a different story...too bad eh.

Let us know how this works out for you please.

Hey Chappy,

Yea what a joke, quick question im running windows vista 64 OEM version on my self build, windows is activated but last time I had to do a roll back it un-activated and had to call up microsoft's auto activation line, If I roll back again and this happens again will it allow me to re-activate, would be the 3rd time + if not looks like I might have to wait for microsoft to pull there finger out and release a fix, at least they have admitted the problem I suppose thats something

P.S Chappy nice choice of case I have the NZXT Lexa Classic also how acurate do you find the temp display on it ?

Hey
