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 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 it 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.

||

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.

|

|
|
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 from TransDimension Inc.

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.
