  11           The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
  12           "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
  13           If your USB host controller supports USB 2.0, you will likely want to
  14           configure this Host Controller Driver.  At the time of this writing,
  15           the primary implementation of EHCI is a chip from NEC, widely available
  16           in add-on PCI cards, but implementations are in the works from other
  17           vendors including Intel and Philips.  Motherboard support is appearing.
  18
  19           EHCI controllers are packaged with "companion" host controllers (OHCI
  20           or UHCI) to handle USB 1.1 devices connected to root hub ports.  Ports
  21           will connect to EHCI if the device is high speed, otherwise they
  22           connect to a companion controller.  If you configure EHCI, you should
  23           probably configure the OHCI (for NEC and some other vendors) USB Host
  24           Controller Driver or UHCI (for Via motherboards) Host Controller
  25           Driver too.

  37           This code is new and hasn't been used with many different
  38           EHCI or USB 2.0 transaction translator implementations.
  39           It should work for ISO-OUT transfers, like audio.

  41 config USB_EHCI_ROOT_HUB_TT

  43         depends on USB_EHCI_HCD && EXPERIMENTAL
  44         ---help---
  45           Some EHCI chips have vendor-specific extensions to integrate
  46           transaction translators, so that no OHCI or UHCI companion
  47           controller is needed.  It's safe to say "y" even if your
  48           controller doesn't support this feature.
  49
  50           This supports the EHCI implementation that's originally
  51           from ARC, and has since changed hands a few times.

  55         depends on USB_EHCI_HCD && EXPERIMENTAL
  56         ---help---
  57           This changes the periodic scheduling code to fill more of the low
  58           and full speed bandwidth available from the Transaction Translator
  59           (TT) in USB 2.0 hubs.  Without this, only one transfer will be
  60           issued in each microframe, significantly reducing the number of
  61           periodic low/fullspeed transfers possible.
  62
  63           If you have multiple periodic low/fullspeed devices connected to a
  64           highspeed USB hub which is connected to a highspeed USB Host
  65           Controller, and some of those devices will not work correctly
  66           (possibly due to "ENOSPC" or "-28" errors), say Y.

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

 132           The Universal Host Controller Interface is a standard by Intel for
 133           accessing the USB hardware in the PC (which is also called the USB
 134           host controller). If your USB host controller conforms to this
 135           standard, you may want to say Y, but see below. All recent boards
 136           with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
 137           i810, i820) conform to this standard. Also all VIA PCI chipsets
 138           (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
