The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
|
|
"high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
|
|
If your USB host controller supports USB 2.0, you will likely want to
|
|
configure this Host Controller Driver. At the time of this writing,
|
|
the primary implementation of EHCI is a chip from NEC, widely available
|
|
in add-on PCI cards, but implementations are in the works from other
|
|
vendors including Intel and Philips. Motherboard support is appearing.
|
|
|
|
EHCI controllers are packaged with "companion" host controllers (OHCI
|
|
or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
|
|
will connect to EHCI if the device is high speed, otherwise they
|
|
connect to a companion controller. If you configure EHCI, you should
|
|
probably configure the OHCI (for NEC and some other vendors) USB Host
|
|
Controller Driver or UHCI (for Via motherboards) Host Controller
|
|
Driver too.
|
|
|
|
You may want to read <file:Documentation/usb/ehci.txt>.
|
|
|
|
To compile this driver as a module, choose M here: the
|
|
module will be called ehci-hcd.

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

|
|
---help---
|
|
Some EHCI chips have vendor-specific extensions to integrate
|
|
transaction translators, so that no OHCI or UHCI companion
|
|
controller is needed. It's safe to say "y" even if your
|
|
controller doesn't support this feature.
|
|
|
|
This supports the EHCI implementation that's originally
|
|
from ARC, and has since changed hands a few times.

|

This changes the periodic scheduling code to fill more of the low
|
|
and full speed bandwidth available from the Transaction Translator
|
|
(TT) in USB 2.0 hubs. Without this, only one transfer will be
|
|
issued in each microframe, significantly reducing the number of
|
|
periodic low/fullspeed transfers possible.
|
|
|
|
If you have multiple periodic low/fullspeed devices connected to a
|
|
highspeed USB hub which is connected to a highspeed USB Host
|
|
Controller, and some of those devices will not work correctly
|
|
(possibly due to "ENOSPC" or "-28" errors), say Y.

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

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

|
The U132 adapter is a USB to CardBus adapter specifically designed
|
|
for PC cards that contain an OHCI host controller. Typical PC cards
|
|
are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
|
|
adapter will *NOT* work with PC cards that do not contain an OHCI
|
|
controller.
|
|
|
|
For those PC cards that contain multiple OHCI controllers only the
|
|
first one is used.
|
|
|
|
The driver consists of two modules, the "ftdi-elan" module is a
|
|
USB client driver that interfaces to the FTDI chip within ELAN's
|
|
USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
|
|
controller driver that talks to the OHCI controller within the
|
|
CardBus cards that are inserted in the U132 adapter.
|
|
|
|
This driver has been tested with a CardBus OHCI USB adapter, and
|
|
worked with a USB PEN Drive inserted into the first USB port of
|
|
the PCCARD. A rather pointless thing to do, but useful for testing.
|
|
|
|
It is safe to say M here.
