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.

41config USB_EHCI_ROOT_HUB_TT
42 bool "Root Hub Transaction Translators (EXPERIMENTAL)"
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.

119 The SL811HS is a single-port USB controller that supports either
120 host side or peripheral side roles. Enable this option if your
121 board has this chip, and you want to use it as a host controller.
