10	---help---
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 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.
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 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.
26
27	  You may want to read <file:Documentation/usb/ehci.txt>.
28
29	  To compile this driver as a module, choose M here: the
30	  module will be called ehci-hcd.

32config USB_EHCI_SPLIT_ISO
33	bool "Full speed ISO transactions (EXPERIMENTAL)"
34	depends on USB_EHCI_HCD && EXPERIMENTAL
35	default n
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.
40
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.

52config USB_ISP116X_HCD
53	tristate "ISP116X HCD support"
54	depends on USB
55	default N
56	---help---
57	  The ISP1160 and ISP1161 chips are USB host controllers. Enable this
58	  option if your board has this chip. If unsure, say N.
59
60	  This driver does not support isochronous transfers.
61
62	  To compile this driver as a module, choose M here: the
63	  module will be called isp116x-hcd.

69	---help---
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.
78
79	  To compile this driver as a module, choose M here: the
80	  module will be called ohci-hcd.

114	---help---
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.

131	help
132	  The SL811HS is a single-port USB controller that supports either
133	  host side or peripheral side roles.  Enable this option if your
134	  board has this chip, and you want to use it as a host controller.
135	  If unsure, say N.
