  78           The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
  79           "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
  80           If your USB host controller supports USB 2.0, you will likely want to
  81           configure this Host Controller Driver.
  82
  83           EHCI controllers are packaged with "companion" host controllers (OHCI
  84           or UHCI) to handle USB 1.1 devices connected to root hub ports.  Ports
  85           will connect to EHCI if the device is high speed, otherwise they
  86           connect to a companion controller.  If you configure EHCI, you should
  87           probably configure the OHCI (for NEC and some other vendors) USB Host
  88           Controller Driver or UHCI (for Via motherboards) Host Controller
  89           Driver too.

 100           Some EHCI chips have vendor-specific extensions to integrate
 101           transaction translators, so that no OHCI or UHCI companion
 102           controller is needed.  It's safe to say "y" even if your
 103           controller doesn't support this feature.

 798           supported by the host controller drivers.

 800           One such test mode is the Embedded High-speed Host Electrical Test
 801           (EHSET) for EHCI host controller hardware, specifically the "Single
 802           Step Set Feature" test.  Typically this will be enabled for On-the-Go
 803           or embedded hosts that need to undergo USB-IF compliance testing with
 804           the aid of special testing hardware.  In the future, this may expand
 805           to include other tests that require support from a HCD driver.
 806
 807           This option is of interest only to developers who need to validate
 808           their USB hardware designs.  It is not needed for normal use.  If
 809           unsure, say N.
