Another big issue users are experiencing after updating their computers with the brand new Windows Vista Service Pack 1 is the USB system not working anymore. This issue involves every USB related device such as: mice, USB dongles, keyboards, external or portable hard disks etc. The USB device is simply not recognized or not detected and the computer returns this message: “Unknown Device”. Microsoft acknowledges this issue even after installing KB938371 and states: “We are aware of concerns that a recent Microsoft update may be causing problems with USB devices. We are investigating the matter, and at this time, do not have any information to share”. Anyway on TechNet forum a guy posted the fix. Here is the trick:
- Go to Control Panel –System and Maintenance — System — Device Manager.
- In the Device Manager, expand the tree of Human Interface Devices.
- Update the driver for all Unknown Device.
- Of course Windows Vista won’t find any new device. When prompted select Browse my computer for driver software.
- Enter or browse to C:\Windows\winsxs as the driver location and press the Next button.
- If the system warns you about unsigned driver, just go on.
- At this point windows Vista should install the right driver for your device.
- Done!
