8 tristate "EHCI HCD (USB 2.0) support"
9 depends on USB && USB_ARCH_HAS_EHCI
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.
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
27 You may want to read <file:Documentation/usb/ehci.txt>.
29 To compile this driver as a module, choose M here: the
30 module will be called ehci-hcd.
32 config USB_EHCI_SPLIT_ISO
33 bool "Full speed ISO transactions (EXPERIMENTAL)"
34 depends on USB_EHCI_HCD && EXPERIMENTAL
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.
41 config USB_EHCI_ROOT_HUB_TT
42 bool "Root Hub Transaction Translators (EXPERIMENTAL)"
43 depends on USB_EHCI_HCD && EXPERIMENTAL
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.
50 This supports the EHCI implementation that's originally
51 from ARC, and has since changed hands a few times.
53 config USB_EHCI_TT_NEWSCHED
54 bool "Improved Transaction Translator scheduling (EXPERIMENTAL)"
55 depends on USB_EHCI_HCD && EXPERIMENTAL
57 This changes the periodic scheduling code to fill more of the low
58 and full speed bandwidth available from the Transaction Translator
59 (TT) in USB 2.0 hubs. Without this, only one transfer will be
60 issued in each microframe, significantly reducing the number of
61 periodic low/fullspeed transfers possible.
63 If you have multiple periodic low/fullspeed devices connected to a
64 highspeed USB hub which is connected to a highspeed USB Host
65 Controller, and some of those devices will not work correctly
66 (possibly due to "ENOSPC" or "-28" errors), say Y.
70 config USB_EHCI_BIG_ENDIAN_MMIO
72 depends on USB_EHCI_HCD
75 config USB_ISP116X_HCD
76 tristate "ISP116X HCD support"
79 The ISP1160 and ISP1161 chips are USB host controllers. Enable this
80 option if your board has this chip. If unsure, say N.
82 This driver does not support isochronous transfers.
84 To compile this driver as a module, choose M here: the
85 module will be called isp116x-hcd.
88 tristate "OHCI HCD support"
89 depends on USB && USB_ARCH_HAS_OHCI
90 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
91 select I2C if ARCH_PNX4008
93 The Open Host Controller Interface (OHCI) is a standard for accessing
94 USB 1.1 host controller hardware. It does more in hardware than Intel's
95 UHCI specification. If your USB host controller follows the OHCI spec,
96 say Y. On most non-x86 systems, and on x86 hardware that's not using a
97 USB controller from Intel or VIA, this is appropriate. If your host
98 controller doesn't use PCI, this is probably appropriate. For a PCI
99 based system where you're not sure, the "lspci -v" entry will list the
100 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
102 To compile this driver as a module, choose M here: the
103 module will be called ohci-hcd.
105 config USB_OHCI_HCD_PPC_SOC
106 bool "OHCI support for on-chip PPC USB controller"
107 depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx)
109 select USB_OHCI_BIG_ENDIAN_DESC
110 select USB_OHCI_BIG_ENDIAN_MMIO
112 Enables support for the USB controller on the MPC52xx or
113 STB03xxx processor chip. If unsure, say Y.
115 config USB_OHCI_HCD_PPC_OF
116 bool "OHCI support for PPC USB controller on OF platform bus"
117 depends on USB_OHCI_HCD && PPC_OF
120 Enables support for the USB controller PowerPC present on the
121 OpenFirmware platform bus.
123 config USB_OHCI_HCD_PPC_OF_BE
124 bool "Support big endian HC"
125 depends on USB_OHCI_HCD_PPC_OF
127 select USB_OHCI_BIG_ENDIAN_DESC
128 select USB_OHCI_BIG_ENDIAN_MMIO
130 config USB_OHCI_HCD_PPC_OF_LE
131 bool "Support little endian HC"
132 depends on USB_OHCI_HCD_PPC_OF
134 select USB_OHCI_LITTLE_ENDIAN
136 config USB_OHCI_HCD_PCI
137 bool "OHCI support for PCI-bus USB controllers"
138 depends on USB_OHCI_HCD && PCI && (STB03xxx || PPC_MPC52xx || USB_OHCI_HCD_PPC_OF)
140 select USB_OHCI_LITTLE_ENDIAN
142 Enables support for PCI-bus plug-in USB controller cards.
145 config USB_OHCI_BIG_ENDIAN_DESC
147 depends on USB_OHCI_HCD
150 config USB_OHCI_BIG_ENDIAN_MMIO
152 depends on USB_OHCI_HCD
155 config USB_OHCI_LITTLE_ENDIAN
157 depends on USB_OHCI_HCD
158 default n if STB03xxx || PPC_MPC52xx
162 tristate "UHCI HCD (most Intel and VIA) support"
163 depends on USB && PCI
165 The Universal Host Controller Interface is a standard by Intel for
166 accessing the USB hardware in the PC (which is also called the USB
167 host controller). If your USB host controller conforms to this
168 standard, you may want to say Y, but see below. All recent boards
169 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
170 i810, i820) conform to this standard. Also all VIA PCI chipsets
171 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
172 133). If unsure, say Y.
174 To compile this driver as a module, choose M here: the
175 module will be called uhci-hcd.
178 tristate "Elan U132 Adapter Host Controller"
179 depends on USB && USB_FTDI_ELAN
182 The U132 adapter is a USB to CardBus adapter specifically designed
183 for PC cards that contain an OHCI host controller. Typical PC cards
184 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
185 adapter will *NOT* work with PC cards that do not contain an OHCI
188 For those PC cards that contain multiple OHCI controllers only the
191 The driver consists of two modules, the "ftdi-elan" module is a
192 USB client driver that interfaces to the FTDI chip within ELAN's
193 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
194 controller driver that talks to the OHCI controller within the
195 CardBus cards that are inserted in the U132 adapter.
197 This driver has been tested with a CardBus OHCI USB adapter, and
198 worked with a USB PEN Drive inserted into the first USB port of
199 the PCCARD. A rather pointless thing to do, but useful for testing.
201 It is safe to say M here.

206 tristate "SL811HS HCD support"
209 The SL811HS is a single-port USB controller that supports either
210 host side or peripheral side roles. Enable this option if your
211 board has this chip, and you want to use it as a host controller.
214 To compile this driver as a module, choose M here: the
215 module will be called sl811-hcd.
218 tristate "CF/PCMCIA support for SL811HS HCD"
219 depends on USB_SL811_HCD && PCMCIA
221 Wraps a PCMCIA driver around the SL811HS HCD, supporting the RATOC
222 REX-CFU1U CF card (often used with PDAs). If unsure, say N.
224 To compile this driver as a module, choose M here: the
225 module will be called "sl811_cs".
