| 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. |

| 36 | ---help--- |
| 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. |

| 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. |

| 56 | ---help--- |
| 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. |
