config USB_EHCI_HCD
        tristate "EHCI HCD (USB 2.0) support"
        ---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.

          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.

config USB_EHCI_ROOT_HUB_TT
        bool "Root Hub Transaction Translators"
        depends on USB_EHCI_HCD
        ---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.

          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.

        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.
