Open Device Manager and expand category Universal Serial Bus Controllers and locate the USB device which is not being recognized by Windows. Right-click on the device and select Uninstall from the context. Unknown devices show up in the Windows Device Manager when Windows can’t identify a piece of hardware and provide a driver for it. An unknown device isn’t just unknown — it’s not functioning until you install the right driver. Windows can identify most devices and download drivers for them automatically. If you have the backup CD with the drivers for your PC or an external device such as a USB printer – (many PC/Laptops are sold with a “Drivers and Utilities Backup” CD, and most external devices come with the CD), this may prove to be the easiest solution for undergoing unknown device driver download (.exe or.zip)!
