  37           The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
  38           "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
  39           If your USB host controller supports USB 2.0, you will likely want to
  40           configure this Host Controller Driver.
  41
  42           EHCI controllers are packaged with "companion" host controllers (OHCI
  43           or UHCI) to handle USB 1.1 devices connected to root hub ports.  Ports
  44           will connect to EHCI if the device is high speed, otherwise they
  45           connect to a companion controller.  If you configure EHCI, you should
  46           probably configure the OHCI (for NEC and some other vendors) USB Host
  47           Controller Driver or UHCI (for Via motherboards) Host Controller
  48           Driver too.

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

 146           The Universal Host Controller Interface is a standard by Intel for
 147           accessing the USB hardware in the PC (which is also called the USB
 148           host controller). If your USB host controller conforms to this
 149           standard, you may want to say Y, but see below. All recent boards
 150           with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
 151           i810, i820) conform to this standard. Also all VIA PCI chipsets
 152           (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
 153           133) and LEON/GRLIB SoCs with the GRUSBHC controller.
 154           If unsure, say Y.
