  39           If your USB host controller supports USB 2.0, you will likely want to
  40           configure this Host Controller Driver.
  41
  42           EHCI controllers are packaged with "companion" host controllers (OHCI
  43           or UHCI) to handle USB 1.1 devices connected to root hub ports.  Ports
  44           will connect to EHCI if the device is high speed, otherwise they
  45           connect to a companion controller.  If you configure EHCI, you should
  46           probably configure the OHCI (for NEC and some other vendors) USB Host
  47           Controller Driver or UHCI (for Via motherboards) Host Controller
  48           Driver too.

  59           Some EHCI chips have vendor-specific extensions to integrate
  60           transaction translators, so that no OHCI or UHCI companion

  62           controller doesn't support this feature.
