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

37 | This code is new and hasn't been used with many different | |
38 | EHCI or USB 2.0 transaction translator implementations. | |
39 | It should work for ISO-OUT transfers, like audio. | |

43 | depends on USB_EHCI_HCD && EXPERIMENTAL | |
44 | ---help--- | |
45 | Some EHCI chips have vendor-specific extensions to integrate | |
46 | transaction translators, so that no OHCI or UHCI companion | |
47 | controller is needed. It's safe to say "y" even if your | |
48 | controller doesn't support this feature. | |
49 | ||
50 | This supports the EHCI implementation from TransDimension Inc. | |

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

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