  48           The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
  49           "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
  50           If your USB host controller supports USB 2.0, you will likely want to
  51           configure this Host Controller Driver.
  52
  53           EHCI controllers are packaged with "companion" host controllers (OHCI
  54           or UHCI) to handle USB 1.1 devices connected to root hub ports.  Ports
  55           will connect to EHCI if the device is high speed, otherwise they
  56           connect to a companion controller.  If you configure EHCI, you should
  57           probably configure the OHCI (for NEC and some other vendors) USB Host
  58           Controller Driver or UHCI (for Via motherboards) Host Controller
  59           Driver too.

  69         ---help---
  70           Some EHCI chips have vendor-specific extensions to integrate
  71           transaction translators, so that no OHCI or UHCI companion

  73           controller doesn't support this feature.
