+ ---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.

+ ---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.

+ ---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.

+ ---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

+ 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.
