  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.

 391           The Open Host Controller Interface (OHCI) is a standard for accessing
 392           USB 1.1 host controller hardware.  It does more in hardware than Intel's
 393           UHCI specification.  If your USB host controller follows the OHCI spec,
 394           say Y.  On most non-x86 systems, and on x86 hardware that's not using a
 395           USB controller from Intel or VIA, this is appropriate.  If your host
 396           controller doesn't use PCI, this is probably appropriate.  For a PCI
 397           based system where you're not sure, the "lspci -v" entry will list the
 398           right "prog-if" for your USB controller(s):  EHCI, OHCI, or UHCI.

 792           Say 'Y' to enable additional software test modes that may be
 793           supported by the host controller drivers.
 794
 795           One such test mode is the Embedded High-speed Host Electrical Test
 796           (EHSET) for EHCI host controller hardware, specifically the "Single
 797           Step Set Feature" test.  Typically this will be enabled for On-the-Go
 798           or embedded hosts that need to undergo USB-IF compliance testing with
 799           the aid of special testing hardware.  In the future, this may expand
 800           to include other tests that require support from a HCD driver.
 801
 802           This option is of interest only to developers who need to validate
 803           their USB hardware designs.  It is not needed for normal use.  If
 804           unsure, say N.
