usb and device manager ....

try to go to the same place and un-install the whole thing and restart . keep in mind after uninstalling you will probably have to re-install the software unless it is PnP (plug n play) for a usb device to operate it must first have a driver to start it...
Hope this works for you go back to device manager and also look in safely remove programs , by the way most thing in properties you can set for quick removal so if you forget to safely remove it won't crash your computer... GOOD LUCK!
