# USB Host Controller Drivers

comment "USB Host Controller Drivers"
depends on USB
config USB_EHCI_HCD
tristate "EHCI HCD (USB 2.0) support"
depends on USB && PCI
---help---
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.
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.
config USB_EHCI_SPLIT_ISO
bool "Full speed ISO transactions (EXPERIMENTAL)"
depends on USB_EHCI_HCD && EXPERIMENTAL
default n
---help---
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.
config USB_EHCI_ROOT_HUB_TT
bool "Root Hub Transaction Translators (EXPERIMENTAL)"
depends on USB_EHCI_HCD && EXPERIMENTAL
---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 from TransDimension Inc.
config USB_OHCI_HCD
tristate "OHCI HCD support"
depends on USB && USB_ARCH_HAS_OHCI
select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
---help---
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.
To compile this driver as a module, choose M here: the
module will be called ohci-hcd.
config USB_OHCI_HCD_PPC_SOC
bool "OHCI support for on-chip PPC USB controller"
depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx)
default y
select USB_OHCI_BIG_ENDIAN
---help---
Enables support for the USB controller on the MPC52xx or
STB03xxx processor chip. If unsure, say Y.
config USB_OHCI_HCD_PCI
bool "OHCI support for PCI-bus USB controllers"
depends on USB_OHCI_HCD && PCI && (STB03xxx || PPC_MPC52xx)
default y
select USB_OHCI_LITTLE_ENDIAN
---help---
Enables support for PCI-bus plug-in USB controller cards.
If unsure, say Y.
config USB_OHCI_BIG_ENDIAN

depends on USB_OHCI_HCD
default n
config USB_OHCI_LITTLE_ENDIAN

config USB_UHCI_HCD
tristate "UHCI HCD (most Intel and VIA) support"
depends on USB && PCI
---help---
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.
To compile this driver as a module, choose M here: the
module will be called uhci-hcd.
config USB_SL811_HCD
tristate "SL811HS HCD support"
depends on USB
default N
help
The SL811HS is a single-port USB controller that supports either
host side or peripheral side roles. Enable this option if your
board has this chip, and you want to use it as a host controller.
If unsure, say N.
To compile this driver as a module, choose M here: the
module will be called sl811-hcd.
