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
Jesper Juhlb3c29d82006-01-10 00:35:22 +010014 configure this Host Controller Driver. At the time of this writing,
15 the primary implementation of EHCI is a chip from NEC, widely available
16 in add-on PCI cards, but implementations are in the works from other
17 vendors including Intel and Philips. Motherboard support is appearing.

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
Jesper Juhlb3c29d82006-01-10 00:35:22 +010021 will connect to EHCI if the device is high speed, otherwise they
Linus Torvalds1da177e2005-04-16 15:20:36 -070022 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.

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

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