USB Host Controller Drivers

USB_C67X00_HCD

Cypress C67x00 HCD support

The Cypress C67x00 (EZ-Host/EZ-OTG) chips are dual-role
host/peripheral/OTG USB controllers.

Enable this option to support this chip in host controller mode.
If unsure, say N.

To compile this driver as a module, choose M here: the
module will be called c67x00.

USB_XHCI_HCD

xHCI HCD (USB 3.0) support (EXPERIMENTAL)

The eXtensible Host Controller Interface (xHCI) is standard for USB 3.0
"SuperSpeed" host controller hardware.

To compile this driver as a module, choose M here: the
module will be called xhci-hcd.

USB_XHCI_HCD_DEBUGGING

Debugging for the xHCI host controller

Say 'Y' to turn on debugging for the xHCI host controller driver.
This will spew debugging output, even in interrupt context.
This should only be used for debugging xHCI driver bugs.

If unsure, say N.

USB_EHCI_HCD

EHCI HCD (USB 2.0) support

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.

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.

USB_EHCI_ROOT_HUB_TT

Root Hub Transaction Translators

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.

USB_EHCI_TT_NEWSCHED

Improved Transaction Translator scheduling

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.  Conversely, if
you have only one such device and it doesn't work, you could try
saying N.

If unsure, say Y.

USB_EHCI_HCD_PMC_MSP

EHCI support for on-chip PMC MSP71xx USB controller

Enables support for the onchip USB controller on the PMC_MSP7100 Family SoC's.
If unsure, say N.

transaction translator built-in. It can be configured to either
support both high speed and full speed devices, or high speed
devices only.

This driver is not supported on boards like trout which
has an external PHY.

USB_OXU210HP_HCD

OXU210HP HCD support

option if your board has this chip. If unsure, say N.

This driver does not support isochronous transfers and doesn't
implement OTG nor USB device controllers.

To compile this driver as a module, choose M here: the
module will be called oxu210hp-hcd.

USB_ISP116X_HCD

ISP116X HCD support

The ISP1160 and ISP1161 chips are USB host controllers. Enable this
option if your board has this chip. If unsure, say N.

module will be called isp1362-hcd.

USB_OHCI_HCD

OHCI HCD support

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.

Enable support for the CNS3XXX SOC's on-chip OHCI controller.
It is needed for low-speed USB 1.0 device support.

USB_UHCI_HCD

UHCI HCD (most Intel and VIA) support

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) and LEON/GRLIB SoCs with the GRUSBHC controller.
If unsure, say Y.

To compile this driver as a module, choose M here: the
module will be called uhci-hcd.

USB_FHCI_HCD

Freescale QE USB Host Controller support

(as found on MPC8360 and MPC8323 processors), the driver supports
Full and Low Speed USB.

FHCI_DEBUG

Freescale QE USB Host Controller debug support

Say "y" to see some FHCI debug information and statistics
through debugfs.

USB_U132_HCD

Elan U132 Adapter Host Controller

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.

USB_SL811_HCD

SL811HS HCD support

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.

USB_SL811_HCD_ISO

partial ISO support

The driver doesn't support iso_frame_desc (yet), but for some simple
devices that just queue one ISO frame per URB, then ISO transfers
"should" work using the normal urb status fields.

If unsure, say N.

USB_SL811_CS

CF/PCMCIA support for SL811HS HCD
