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

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

 784           Say 'Y' to enable additional software test modes that may be
 785           supported by the host controller drivers.
 786
 787           One such test mode is the Embedded High-speed Host Electrical Test
 788           (EHSET) for EHCI host controller hardware, specifically the "Single
 789           Step Set Feature" test.  Typically this will be enabled for On-the-Go
 790           or embedded hosts that need to undergo USB-IF compliance testing with
 791           the aid of special testing hardware.  In the future, this may expand
 792           to include other tests that require support from a HCD driver.
 793
 794           This option is of interest only to developers who need to validate
 795           their USB hardware designs.  It is not needed for normal use.  If
 796           unsure, say N.
