It seems fairly common in Win8. Seems to be some sort of conflict in the USB port.

Two things that would be relatively safe to try:

Run CCleaner (some people have luck with just the "cleaner" part and others also run the "registry" part). Registry cleaners are generally not recommend but I have used CCleaner for years and never once had a problem. Note: Read the installation screens carefully because they bundle an offer for Chrome browser into the installation program and you have to untick the box to avoid downloading Chrome. The CCleaner program is still good and worth the annoyance of having to untick that box during install.

The other would USBdeviceView. It is a bit more technical but it just gives you a list of all USB devices that have ever been attached to your computer. It is safe to delete any on the list (except ones with a green dot which indicates they are currently connected). Any devices you delete will just be added the next time you connect the device. You don't have to delete them all but anything you don't recognize or haven't used in a while is probably best deleted.

I can't guarantee that either option will work but I have used both programs in the past and they are safe. Let me know if you want/need more detail.
