| ---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 the time of 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 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. |

| 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 that's originally |
| from ARC, and has since changed hands a few times. |
| |
| config USB_EHCI_TT_NEWSCHED |
| bool "Improved Transaction Translator scheduling (EXPERIMENTAL)" |
| depends on USB_EHCI_HCD && EXPERIMENTAL |
| ---help--- |
| 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. |
| |
| If unsure, say N. |

| ---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. |

| 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. |

| config USB_U132_HCD |
| tristate "Elan U132 Adapter Host Controller" |
| depends on USB && USB_FTDI_ELAN |
| default M |
| help |
| 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. |
