  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
  72           controller is needed.  It's safe to say "y" even if your
  73           controller doesn't support this feature.

  87           periodic low/fullspeed transfers possible.

 470           The U132 adapter is a USB to CardBus adapter specifically designed

 472           are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132

 479           The driver consists of two modules, the "ftdi-elan" module is a
 480           USB client driver that interfaces to the FTDI chip within ELAN's
 481           USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
 482           controller driver that talks to the OHCI controller within the
 483           CardBus cards that are inserted in the U132 adapter.
 484
 485           This driver has been tested with a CardBus OHCI USB adapter, and
 486           worked with a USB PEN Drive inserted into the first USB port of
 487           the PCCARD. A rather pointless thing to do, but useful for testing.
