8 tristate "Cypress C67x00 HCD support"
11 The Cypress C67x00 (EZ-Host/EZ-OTG) chips are dual-role
12 host/peripheral/OTG USB controllers.
14 Enable this option to support this chip in host controller mode.
17 To compile this driver as a module, choose M here: the
18 module will be called c67x00.
21 tristate "xHCI HCD (USB 3.0) support (EXPERIMENTAL)"
22 depends on USB && PCI && EXPERIMENTAL
24 The eXtensible Host Controller Interface (xHCI) is standard for USB 3.0
25 "SuperSpeed" host controller hardware.
27 To compile this driver as a module, choose M here: the
28 module will be called xhci-hcd.
30 config USB_XHCI_HCD_DEBUGGING
31 bool "Debugging for the xHCI host controller"
32 depends on USB_XHCI_HCD
34 Say 'Y' to turn on debugging for the xHCI host controller driver.
35 This will spew debugging output, even in interrupt context.
36 This should only be used for debugging xHCI driver bugs.
41 tristate "EHCI HCD (USB 2.0) support"
42 depends on USB && USB_ARCH_HAS_EHCI
44 The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
45 "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
46 If your USB host controller supports USB 2.0, you will likely want to
47 configure this Host Controller Driver.
49 EHCI controllers are packaged with "companion" host controllers (OHCI
50 or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
51 will connect to EHCI if the device is high speed, otherwise they
52 connect to a companion controller. If you configure EHCI, you should
53 probably configure the OHCI (for NEC and some other vendors) USB Host
54 Controller Driver or UHCI (for Via motherboards) Host Controller
57 You may want to read <file:Documentation/usb/ehci.txt>.
59 To compile this driver as a module, choose M here: the
60 module will be called ehci-hcd.
62 config USB_EHCI_ROOT_HUB_TT
63 bool "Root Hub Transaction Translators"
64 depends on USB_EHCI_HCD
66 Some EHCI chips have vendor-specific extensions to integrate
67 transaction translators, so that no OHCI or UHCI companion
68 controller is needed. It's safe to say "y" even if your
69 controller doesn't support this feature.
71 This supports the EHCI implementation that's originally
72 from ARC, and has since changed hands a few times.
74 config USB_EHCI_TT_NEWSCHED
75 bool "Improved Transaction Translator scheduling (EXPERIMENTAL)"
76 depends on USB_EHCI_HCD && EXPERIMENTAL
78 This changes the periodic scheduling code to fill more of the low
79 and full speed bandwidth available from the Transaction Translator
80 (TT) in USB 2.0 hubs. Without this, only one transfer will be
81 issued in each microframe, significantly reducing the number of
82 periodic low/fullspeed transfers possible.
84 If you have multiple periodic low/fullspeed devices connected to a
85 highspeed USB hub which is connected to a highspeed USB Host
86 Controller, and some of those devices will not work correctly
87 (possibly due to "ENOSPC" or "-28" errors), say Y.

93 depends on USB_EHCI_HCD && (PPC_CELLEB || PPC_PS3 || 440EPX || ARCH_IXP4XX || XPS_USB_HCD_XILINX)

104 select USB_EHCI_BIG_ENDIAN_DESC
105 select USB_EHCI_BIG_ENDIAN_MMIO
107 Xilinx xps USB host controller core is EHCI compilant and has
108 transaction translator built-in. It can be configured to either
109 support both high speed and full speed devices, or high speed
113 bool "Support for Freescale on-chip EHCI USB controller"
114 depends on USB_EHCI_HCD && FSL_SOC
115 select USB_EHCI_ROOT_HUB_TT
117 Variation of ARC USB block used in some Freescale chips.
120 bool "Support for Freescale on-chip EHCI USB controller"
121 depends on USB_EHCI_HCD && ARCH_MXC
122 select USB_EHCI_ROOT_HUB_TT
124 Variation of ARC USB block used in some Freescale chips.
126 config USB_EHCI_HCD_PPC_OF
127 bool "EHCI support for PPC USB controller on OF platform bus"
128 depends on USB_EHCI_HCD && PPC_OF
131 Enables support for the USB controller present on the PowerPC
132 OpenFirmware platform bus.
134 config USB_W90X900_EHCI
135 bool "W90X900(W90P910) EHCI support"
136 depends on USB_EHCI_HCD && ARCH_W90X900
138 Enables support for the W90X900 USB controller
140 config USB_OXU210HP_HCD
141 tristate "OXU210HP HCD support"
144 The OXU210HP is an USB host/OTG/device controller. Enable this
145 option if your board has this chip. If unsure, say N.
147 This driver does not support isochronous transfers and doesn't
148 implement OTG nor USB device controllers.
150 To compile this driver as a module, choose M here: the
151 module will be called oxu210hp-hcd.
153 config USB_ISP116X_HCD
154 tristate "ISP116X HCD support"
157 The ISP1160 and ISP1161 chips are USB host controllers. Enable this
158 option if your board has this chip. If unsure, say N.
160 This driver does not support isochronous transfers.
162 To compile this driver as a module, choose M here: the
163 module will be called isp116x-hcd.
165 config USB_ISP1760_HCD
166 tristate "ISP 1760 HCD support"
167 depends on USB && EXPERIMENTAL
169 The ISP1760 chip is a USB 2.0 host controller.
171 This driver does not support isochronous transfers or OTG.
172 This USB controller is usually attached to a non-DMA-Master
173 capable bus. NXP's eval kit brings this chip on PCI card
174 where the chip itself is behind a PLB to simulate such

178 module will be called isp1760.
180 config USB_ISP1362_HCD
181 tristate "ISP1362 HCD support"
185 Supports the Philips ISP1362 chip as a host controller
187 This driver does not support isochronous transfers.
189 To compile this driver as a module, choose M here: the
190 module will be called isp1362-hcd.
193 tristate "OHCI HCD support"
194 depends on USB && USB_ARCH_HAS_OHCI
195 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
196 select USB_OTG_UTILS if ARCH_OMAP
198 The Open Host Controller Interface (OHCI) is a standard for accessing
199 USB 1.1 host controller hardware. It does more in hardware than Intel's
200 UHCI specification. If your USB host controller follows the OHCI spec,
201 say Y. On most non-x86 systems, and on x86 hardware that's not using a
202 USB controller from Intel or VIA, this is appropriate. If your host
203 controller doesn't use PCI, this is probably appropriate. For a PCI
204 based system where you're not sure, the "lspci -v" entry will list the
205 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
207 To compile this driver as a module, choose M here: the
208 module will be called ohci-hcd.

234 Enables support for little-endian USB controllers present on the
235 OpenFirmware platform bus.

281 tristate "UHCI HCD (most Intel and VIA) support"
282 depends on USB && PCI
284 The Universal Host Controller Interface is a standard by Intel for
285 accessing the USB hardware in the PC (which is also called the USB
286 host controller). If your USB host controller conforms to this
287 standard, you may want to say Y, but see below. All recent boards
288 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
289 i810, i820) conform to this standard. Also all VIA PCI chipsets
290 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
291 133). If unsure, say Y.

294 module will be called uhci-hcd.

303 (as found on MPC8360 and MPC8323 processors), the driver supports
304 Full and Low Speed USB.
307 bool "Freescale QE USB Host Controller debug support"
308 depends on USB_FHCI_HCD && DEBUG_FS
310 Say "y" to see some FHCI debug information and statistics
314 tristate "Elan U132 Adapter Host Controller"
315 depends on USB && USB_FTDI_ELAN
318 The U132 adapter is a USB to CardBus adapter specifically designed
319 for PC cards that contain an OHCI host controller. Typical PC cards
320 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
321 adapter will *NOT* work with PC cards that do not contain an OHCI
324 For those PC cards that contain multiple OHCI controllers only the
327 The driver consists of two modules, the "ftdi-elan" module is a
328 USB client driver that interfaces to the FTDI chip within ELAN's
329 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
330 controller driver that talks to the OHCI controller within the
331 CardBus cards that are inserted in the U132 adapter.
333 This driver has been tested with a CardBus OHCI USB adapter, and
334 worked with a USB PEN Drive inserted into the first USB port of
335 the PCCARD. A rather pointless thing to do, but useful for testing.
337 It is safe to say M here.
