  60           If your USB host controller supports USB 2.0, you will likely want to
  61           configure this Host Controller Driver.
  62
  63           EHCI controllers are packaged with "companion" host controllers (OHCI
  64           or UHCI) to handle USB 1.1 devices connected to root hub ports.  Ports
  65           will connect to EHCI if the device is high speed, otherwise they
  66           connect to a companion controller.  If you configure EHCI, you should
  67           probably configure the OHCI (for NEC and some other vendors) USB Host
  68           Controller Driver or UHCI (for Via motherboards) Host Controller
  69           Driver too.

 769           Enable support for the EHCI and OCHI host controller on an bcma bus.
 770           It converts the bcma driver into two platform device drivers
 771           for ehci and ohci.

 773           If unsure, say N.

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