30	  The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
31	  "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
32	  If your USB host controller supports USB 2.0, you will likely want to
33	  configure this Host Controller Driver.
34
35	  EHCI controllers are packaged with "companion" host controllers (OHCI
36	  or UHCI) to handle USB 1.1 devices connected to root hub ports.  Ports
37	  will connect to EHCI if the device is high speed, otherwise they
38	  connect to a companion controller.  If you configure EHCI, you should
39	  probably configure the OHCI (for NEC and some other vendors) USB Host
40	  Controller Driver or UHCI (for Via motherboards) Host Controller
41	  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.
