USB Device not recognised

When the "USB Device not recognised" window opened this morning, we followed all the instructions to remedy this. We only have 3 things attached: the cordless mouse+keyboard, the printer, and the camera.
Device Manager reports no problems. But in the USB section, the fourth one down says: unknown device.
We've unplugged and re-plugged each cable; and then we've tried each in a different port. We've checked the drivers are up-to-date. We've tried re-starting the pc. We've run malware and virus scans. We've run Ccleaner.
But the pesky message STILL keeps popping up!
Please - does anyone know how we can sort this problem? Thanks!

what version of winodws are you using, if its xp may be if you reinstall the drivers disc and see if it remedy's the problem.

Im presuming the device use to work on usb connection b4 this morning. also right click on my computer and go to properties and hardware device manager and look at the usb connections and enable them but try reinstalling the drivers first.

In device manager Uninstall EVERYTHING under the heading USB,
reboot the PC let XP find and install new hardware.
Your equipment should now be recognised.

Do you have a built in card reader that is attached to an internal USB port on a header on your motherboard. If so that could be the "USB Device not recognised" Then follow Fruit Bat /\0/\'s advice

Would there be a drivers disk,i thought these drivers are part of windows,as mine have allways been.

Thanks very very much for all your support!
We downloaded RegCure, (thanks, Sea Urchin) and it flagged up all sorts of problems, but then said the free version couldn't sort them; we'd have to buy the full version. So before doing that, we thought about ronalddonald's and Fruit Bat's suggestions. We uninstalled the USB device that was shown as problematic in Device Manager, re-booted, and let it reinstall. It still said it was an unknown device while the desktop was loading, but the little window then vanished and now it's quiet.... fingers crossed that's done the trick!
In case this helps anyone else: we're running XP and don't have a built-in card-reader, and the errant USB slot said it didn't have a driver, so we couldn't update it.
I'll report back in a few days to say if the problem's gone. Thanks to all of you, so much.

I didn't knowingly recommend RegCure - although I now see it shown on that link as a download. I was actually suggesting you read the article, where the author explained how he overcame your problem. Sorry I didn't make it clear - in fact I wouldn't recommend RegCure for the very reason that you discovered, plus the fact that it can sometimes cause more problems than it solves IMO.

Sea Urchin - many thanks, plus apologies! We revisited your link and read lower down the page, and followed the advice. We just switched off the pc and unplugged it, and then switched it all on again after a while. So far, so good! (And we've uninstalled RegCure.)
The previous uninstalling-of-USB remedy looked very promising at first, but didn't last, alas. Again, we'll see what happens over the next few days and will report back! Thank you so much for your help.

Will look forward to hearing in the next few days whether it seems to have worked
