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.
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.
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.
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.
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. Conversely, if you have only one such device and it doesn't work, you could try saying N. If unsure, say Y.
Enables support for the onchip USB controller on the PMC_MSP7100 Family SoC's. If unsure, say N.
Xilinx xps USB host controller core is EHCI compilant and has transaction translator built-in. It can be configured to either support both high speed and full speed devices, or high speed devices only.

The OXU210HP is an USB host/OTG/device controller. Enable this option if your board has this chip. If unsure, say N.

The ISP1760 chip is a USB 2.0 host controller. This driver does not support isochronous transfers or OTG. This USB controller is usually attached to a non-DMA-Master capable bus. NXP's eval kit brings this chip on PCI card where the chip itself is behind a PLB to simulate such a bus. To compile this driver as a module, choose M here: the module will be called isp1760.

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.

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.

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. See also <http://www.elandigitalsystems.com/support/ufaq/u132linux.php>
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.
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.
