USB Malfunction-No USB in use


[link to this post] 		 
I keep getting a pop up which says.....

"one of the USB device attached to this computer has malfunctioned, and Windows does not recognise it"

However there is nothing attached to any of the USB ports.

Any ideas what is causing it? Am running Windows 7 Pro.

Do you have a multi-way camera card reader? They are on USB.

Yes I do have one of those but in the Device Manager it is showing an "unknown device" which has the yellow exclamation mark on it, not the card reader.

Check your usb ports for damage, check all devices connected by USB, you will most likely get to the cause.

All USB ports are working fine as in the card reader.

Go back into device manager.
Highlight the unknown device and hit the delete button.

With any luck when you reboot the computer the problem will go away.

I've had this prob for the last year or so (Win7). Doesn't seem to cause any harm other than mild annoyance.

Have you tried upgrading the motherboard's firmware and/or installing the manufacturer's drivers. Microsoft's drivers do not always work correctly.
