  67           If your USB host controller supports USB 2.0, you will likely want to
  68           configure this Host Controller Driver.
  69
  70           EHCI controllers are packaged with "companion" host controllers (OHCI
  71           or UHCI) to handle USB 1.1 devices connected to root hub ports.  Ports
  72           will connect to EHCI if the device is high speed, otherwise they
  73           connect to a companion controller.  If you configure EHCI, you should
  74           probably configure the OHCI (for NEC and some other vendors) USB Host
  75           Controller Driver or UHCI (for Via motherboards) Host Controller
  76           Driver too.

 775           Say 'Y' to enable additional software test modes that may be
 776           supported by the host controller drivers.
 777
 778           One such test mode is the Embedded High-speed Host Electrical Test
 779           (EHSET) for EHCI host controller hardware, specifically the "Single
 780           Step Set Feature" test.  Typically this will be enabled for On-the-Go
 781           or embedded hosts that need to undergo USB-IF compliance testing with
 782           the aid of special testing hardware.  In the future, this may expand
 783           to include other tests that require support from a HCD driver.
 784
 785           This option is of interest only to developers who need to validate
 786           their USB hardware designs.  It is not needed for normal use.  If
 787           unsure, say N.
