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_ROOT_HUB_TT
33 bool "Root Hub Transaction Translators (EXPERIMENTAL)"
34 depends on USB_EHCI_HCD && EXPERIMENTAL
36 Some EHCI chips have vendor-specific extensions to integrate
37 transaction translators, so that no OHCI or UHCI companion
38 controller is needed. It's safe to say "y" even if your
39 controller doesn't support this feature.
41 This supports the EHCI implementation that's originally
42 from ARC, and has since changed hands a few times.
44 config USB_EHCI_TT_NEWSCHED
45 bool "Improved Transaction Translator scheduling (EXPERIMENTAL)"
46 depends on USB_EHCI_HCD && EXPERIMENTAL
48 This changes the periodic scheduling code to fill more of the low
49 and full speed bandwidth available from the Transaction Translator
50 (TT) in USB 2.0 hubs. Without this, only one transfer will be
51 issued in each microframe, significantly reducing the number of
52 periodic low/fullspeed transfers possible.
54 If you have multiple periodic low/fullspeed devices connected to a
55 highspeed USB hub which is connected to a highspeed USB Host
56 Controller, and some of those devices will not work correctly
57 (possibly due to "ENOSPC" or "-28" errors), say Y.

87 config USB_EHCI_HCD_PPC_OF
88 bool "EHCI support for PPC USB controller on OF platform bus"
89 depends on USB_EHCI_HCD && PPC_OF
92 Enables support for the USB controller present on the PowerPC
93 OpenFirmware platform bus.
95 config USB_ISP116X_HCD
96 tristate "ISP116X HCD support"
99 The ISP1160 and ISP1161 chips are USB host controllers. Enable this
100 option if your board has this chip. If unsure, say N.
102 This driver does not support isochronous transfers.
104 To compile this driver as a module, choose M here: the
105 module will be called isp116x-hcd.
108 tristate "OHCI HCD support"
109 depends on USB && USB_ARCH_HAS_OHCI
110 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
111 select I2C if ARCH_PNX4008
113 The Open Host Controller Interface (OHCI) is a standard for accessing
114 USB 1.1 host controller hardware. It does more in hardware than Intel's
115 UHCI specification. If your USB host controller follows the OHCI spec,
116 say Y. On most non-x86 systems, and on x86 hardware that's not using a
117 USB controller from Intel or VIA, this is appropriate. If your host
118 controller doesn't use PCI, this is probably appropriate. For a PCI
119 based system where you're not sure, the "lspci -v" entry will list the
120 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
122 To compile this driver as a module, choose M here: the
123 module will be called ohci-hcd.

130 select USB_OHCI_BIG_ENDIAN_MMIO
132 Enables support for the USB controller on the MPC52xx or
133 STB03xxx processor chip. If unsure, say Y.

195 tristate "UHCI HCD (most Intel and VIA) support"
196 depends on USB && PCI
198 The Universal Host Controller Interface is a standard by Intel for
199 accessing the USB hardware in the PC (which is also called the USB
200 host controller). If your USB host controller conforms to this
201 standard, you may want to say Y, but see below. All recent boards
202 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
203 i810, i820) conform to this standard. Also all VIA PCI chipsets
204 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
205 133). If unsure, say Y.
207 To compile this driver as a module, choose M here: the
208 module will be called uhci-hcd.
211 tristate "Elan U132 Adapter Host Controller"
212 depends on USB && USB_FTDI_ELAN
215 The U132 adapter is a USB to CardBus adapter specifically designed
216 for PC cards that contain an OHCI host controller. Typical PC cards
217 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
218 adapter will *NOT* work with PC cards that do not contain an OHCI
221 For those PC cards that contain multiple OHCI controllers only the
224 The driver consists of two modules, the "ftdi-elan" module is a
225 USB client driver that interfaces to the FTDI chip within ELAN's
226 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
227 controller driver that talks to the OHCI controller within the
228 CardBus cards that are inserted in the U132 adapter.
230 This driver has been tested with a CardBus OHCI USB adapter, and
231 worked with a USB PEN Drive inserted into the first USB port of
232 the PCCARD. A rather pointless thing to do, but useful for testing.
234 It is safe to say M here.

239 tristate "SL811HS HCD support"
242 The SL811HS is a single-port USB controller that supports either
243 host side or peripheral side roles. Enable this option if your
244 board has this chip, and you want to use it as a host controller.
247 To compile this driver as a module, choose M here: the
248 module will be called sl811-hcd.
251 tristate "CF/PCMCIA support for SL811HS HCD"
252 depends on USB_SL811_HCD && PCMCIA
254 Wraps a PCMCIA driver around the SL811HS HCD, supporting the RATOC
255 REX-CFU1U CF card (often used with PDAs). If unsure, say N.
257 To compile this driver as a module, choose M here: the
258 module will be called "sl811_cs".
260 config USB_R8A66597_HCD
261 tristate "R8A66597 HCD support"
264 The R8A66597 is a USB 2.0 host and peripheral controller.
266 Enable this option if your board has this chip, and you want
267 to use it as a host controller. If unsure, say N.
269 To compile this driver as a module, choose M here: the
270 module will be called r8a66597-hcd.
