title: Cant remove oem.inf
body: <p>I am trying to remove a USB controller, but I am facing the following problem:</p>
  
  <p>I opened a windows console as administrator and run <code>pnputil -e</code> to get the complete list of controllers installed</p>
  
  <p>The controller I want to uninstall showed up as oem38.inf</p>
  
  <p>I executed: <code>pnputil -f -d oem38.inf</code> to remove it, but got an error saying that it cant be uninstalled because the specified filename is not an installed OEM INF.</p>
  
  <p>Any idea on how can I fix this?</p>
  
  <p>My O.S is: Windows 7 Ultimate - Service Pack 1</p>
  
  <p>Thanks</p>
