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.
91 config USB_EHCI_BIG_ENDIAN_MMIO
93 depends on USB_EHCI_HCD && (PPC_CELLEB || PPC_PS3 || 440EPX || ARCH_IXP4XX)
96 config USB_EHCI_BIG_ENDIAN_DESC

102 bool "Support for Freescale on-chip EHCI USB controller"
103 depends on USB_EHCI_HCD && FSL_SOC
104 select USB_EHCI_ROOT_HUB_TT
106 Variation of ARC USB block used in some Freescale chips.

109 bool "EHCI support for PPC USB controller on OF platform bus"
110 depends on USB_EHCI_HCD && PPC_OF
113 Enables support for the USB controller present on the PowerPC
114 OpenFirmware platform bus.
116 config USB_OXU210HP_HCD
117 tristate "OXU210HP HCD support"
120 The OXU210HP is an USB host/OTG/device controller. Enable this
121 option if your board has this chip. If unsure, say N.
123 This driver does not support isochronous transfers and doesn't
124 implement OTG nor USB device controllers.
126 To compile this driver as a module, choose M here: the
127 module will be called oxu210hp-hcd.
129 config USB_ISP116X_HCD
130 tristate "ISP116X HCD support"
133 The ISP1160 and ISP1161 chips are USB host controllers. Enable this
134 option if your board has this chip. If unsure, say N.
136 This driver does not support isochronous transfers.
138 To compile this driver as a module, choose M here: the
139 module will be called isp116x-hcd.
141 config USB_ISP1760_HCD
142 tristate "ISP 1760 HCD support"
143 depends on USB && EXPERIMENTAL
145 The ISP1760 chip is a USB 2.0 host controller.
147 This driver does not support isochronous transfers or OTG.
148 This USB controller is usually attached to a non-DMA-Master
149 capable bus. NXP's eval kit brings this chip on PCI card
150 where the chip itself is behind a PLB to simulate such
153 To compile this driver as a module, choose M here: the
154 module will be called isp1760.
157 tristate "OHCI HCD support"
158 depends on USB && USB_ARCH_HAS_OHCI
159 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
160 select USB_OTG_UTILS if ARCH_OMAP
162 The Open Host Controller Interface (OHCI) is a standard for accessing
163 USB 1.1 host controller hardware. It does more in hardware than Intel's
164 UHCI specification. If your USB host controller follows the OHCI spec,
165 say Y. On most non-x86 systems, and on x86 hardware that's not using a
166 USB controller from Intel or VIA, this is appropriate. If your host
167 controller doesn't use PCI, this is probably appropriate. For a PCI
168 based system where you're not sure, the "lspci -v" entry will list the
169 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
171 To compile this driver as a module, choose M here: the
172 module will be called ohci-hcd.
174 config USB_OHCI_HCD_PPC_SOC

182 STB03xxx processor chip. If unsure, say Y.
184 config USB_OHCI_HCD_PPC_OF
185 bool "OHCI support for PPC USB controller on OF platform bus"
186 depends on USB_OHCI_HCD && PPC_OF
189 Enables support for the USB controller PowerPC present on the
190 OpenFirmware platform bus.
192 config USB_OHCI_HCD_PPC_OF_BE

244 tristate "UHCI HCD (most Intel and VIA) support"
245 depends on USB && PCI
247 The Universal Host Controller Interface is a standard by Intel for
248 accessing the USB hardware in the PC (which is also called the USB
249 host controller). If your USB host controller conforms to this
250 standard, you may want to say Y, but see below. All recent boards
251 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
252 i810, i820) conform to this standard. Also all VIA PCI chipsets
253 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
254 133). If unsure, say Y.

267 Full and Low Speed USB.
270 bool "Freescale QE USB Host Controller debug support"
271 depends on USB_FHCI_HCD && DEBUG_FS
273 Say "y" to see some FHCI debug information and statistics
277 tristate "Elan U132 Adapter Host Controller"
278 depends on USB && USB_FTDI_ELAN
281 The U132 adapter is a USB to CardBus adapter specifically designed
282 for PC cards that contain an OHCI host controller. Typical PC cards
283 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
284 adapter will *NOT* work with PC cards that do not contain an OHCI
287 For those PC cards that contain multiple OHCI controllers only the
290 The driver consists of two modules, the "ftdi-elan" module is a
291 USB client driver that interfaces to the FTDI chip within ELAN's
292 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
293 controller driver that talks to the OHCI controller within the
294 CardBus cards that are inserted in the U132 adapter.
296 This driver has been tested with a CardBus OHCI USB adapter, and
297 worked with a USB PEN Drive inserted into the first USB port of
298 the PCCARD. A rather pointless thing to do, but useful for testing.
300 It is safe to say M here.
