  10. The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
  11. "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
  12. If your USB host controller supports USB 2.0, you will likely want to
  13. configure this Host Controller Driver. At the time of this writing,
  14. the primary implementation of EHCI is a chip from NEC, widely available
  15. in add-on PCI cards, but implementations are in the works from other
  16. vendors including Intel and Philips. Motherboard support is appearing.
  17. EHCI controllers are packaged with "companion" host controllers (OHCI
  18. or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
  19. will connect to EHCI if the device is high speed, otherwise they
  20. connect to a companion controller. If you configure EHCI, you should
  21. probably configure the OHCI (for NEC and some other vendors) USB Host
  22. Controller Driver or UHCI (for Via motherboards) Host Controller
  23. Driver too.
  24. You may want to read <file:Documentation/usb/ehci.txt>.
  25. To compile this driver as a module, choose M here: the
  26. module will be called ehci-hcd.

  32. This code is new and hasn't been used with many different
  33. EHCI or USB 2.0 transaction translator implementations.
  34. It should work for ISO-OUT transfers, like audio.
  35. config USB_EHCI_ROOT_HUB_TT
  36. bool "Root Hub Transaction Translators (EXPERIMENTAL)"
  37. depends on USB_EHCI_HCD && EXPERIMENTAL
  38. ---help---
  39. Some EHCI chips have vendor-specific extensions to integrate
  40. transaction translators, so that no OHCI or UHCI companion
  41. controller is needed. It's safe to say "y" even if your
  42. controller doesn't support this feature.
  43. This supports the EHCI implementation that's originally
  44. from ARC, and has since changed hands a few times.
  45. config USB_EHCI_TT_NEWSCHED
  46. bool "Improved Transaction Translator scheduling (EXPERIMENTAL)"
  47. depends on USB_EHCI_HCD && EXPERIMENTAL
  48. ---help---
  49. This changes the periodic scheduling code to fill more of the low
  50. and full speed bandwidth available from the Transaction Translator
  51. (TT) in USB 2.0 hubs. Without this, only one transfer will be
  52. issued in each microframe, significantly reducing the number of
  53. periodic low/fullspeed transfers possible.
  54. If you have multiple periodic low/fullspeed devices connected to a
  55. highspeed USB hub which is connected to a highspeed USB Host
  56. Controller, and some of those devices will not work correctly
  57. (possibly due to "ENOSPC" or "-28" errors), say Y.

  89. The Open Host Controller Interface (OHCI) is a standard for accessing
  90. USB 1.1 host controller hardware. It does more in hardware than Intel's
  91. UHCI specification. If your USB host controller follows the OHCI spec,
  92. say Y. On most non-x86 systems, and on x86 hardware that's not using a
  93. USB controller from Intel or VIA, this is appropriate. If your host
  94. controller doesn't use PCI, this is probably appropriate. For a PCI
  95. based system where you're not sure, the "lspci -v" entry will list the
  96. right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.

  161. The Universal Host Controller Interface is a standard by Intel for
  162. accessing the USB hardware in the PC (which is also called the USB
  163. host controller). If your USB host controller conforms to this
  164. standard, you may want to say Y, but see below. All recent boards
  165. with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
  166. i810, i820) conform to this standard. Also all VIA PCI chipsets
  167. (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
  168. 133). If unsure, say Y.

  176. The U132 adapter is a USB to CardBus adapter specifically designed
  177. for PC cards that contain an OHCI host controller. Typical PC cards
  178. are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
  179. adapter will *NOT* work with PC cards that do not contain an OHCI
  180. controller.
  181. For those PC cards that contain multiple OHCI controllers only the
  182. first one is used.
  183. The driver consists of two modules, the "ftdi-elan" module is a
  184. USB client driver that interfaces to the FTDI chip within ELAN's
  185. USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
  186. controller driver that talks to the OHCI controller within the
  187. CardBus cards that are inserted in the U132 adapter.
  188. This driver has been tested with a CardBus OHCI USB adapter, and
  189. worked with a USB PEN Drive inserted into the first USB port of
  190. the PCCARD. A rather pointless thing to do, but useful for testing.
  191. It is safe to say M here.
