   On some devices, this is "HIPM" and "DIPM" on SATA,   
   LSPM on PCIe.   
      
   There is ASPM as well for PCie. (A Dell BIOS setting)

   When one of these causes grief, I set it to the "always running"

   USB Hubs seem to have traps doors too, but I don't   
   know the names to look that up. Linux can shut off a hub   
   in such a way, that normal Windows discovery won't override it.
