   Then you are a lucky man and there is nothing for you to do !   
      
   It's all so damn complicated to correctly INITIALIZE the HC HW: there is a    
   relationship between an EHCI host controller and   
   its associcated UHCI/OHCI "companion" host controllers. I am not sure but    
   they even might partially share the very same HW !   
   On some systems it's important that the EHCI host controllers claims    
   ownership of the HC BEFORE the companion controller has a chance to do the    
   same. On other systems this does not seem to matter.   
   The USB specs for UHCI/OHCI/EHCI don't really go into this level of detail    
   to be of any help. It's all trial and error.   
      
   For USBD.SYS: I recently added some stuff that brings it closer to the IBM    
   driver (while also having introduced a fix that is NOT in the IBM driver +    
   some other optimizations + "to be on the safe side" changes).   
   Now, the driver might even be in the same shape as the 10.162 driver. But    
   again, for some people, this modified driver does not properly work compared    
   to the IBM driver. It needs more feedback. It's in its early stages.
