  31         ---help---
  32           The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
  33           "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
  34           If your USB host controller supports USB 2.0, you will likely want to
  35           configure this Host Controller Driver.
  36
  37           EHCI controllers are packaged with "companion" host controllers (OHCI
  38           or UHCI) to handle USB 1.1 devices connected to root hub ports.  Ports
  39           will connect to EHCI if the device is high speed, otherwise they
  40           connect to a companion controller.  If you configure EHCI, you should
  41           probably configure the OHCI (for NEC and some other vendors) USB Host
  42           Controller Driver or UHCI (for Via motherboards) Host Controller
  43           Driver too.
