  59           "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
  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.

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

 790           Say 'Y' to enable additional software test modes that may be
 791           supported by the host controller drivers.

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