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"
76 depends on USB_EHCI_HCD
79 This changes the periodic scheduling code to fill more of the low
80 and full speed bandwidth available from the Transaction Translator
81 (TT) in USB 2.0 hubs. Without this, only one transfer will be
82 issued in each microframe, significantly reducing the number of
83 periodic low/fullspeed transfers possible.
85 If you have multiple periodic low/fullspeed devices connected to a
86 highspeed USB hub which is connected to a highspeed USB Host
87 Controller, and some of those devices will not work correctly
88 (possibly due to "ENOSPC" or "-28" errors), say Y. Conversely, if
89 you have only one such device and it doesn't work, you could try

111 transaction translator built-in. It can be configured to either
112 support both high speed and full speed devices, or high speed

117 depends on USB_EHCI_HCD && FSL_SOC
118 select USB_EHCI_ROOT_HUB_TT

124 depends on USB_EHCI_HCD && ARCH_MXC
125 select USB_EHCI_ROOT_HUB_TT
127 Variation of ARC USB block used in some Freescale chips.
129 config USB_EHCI_HCD_PPC_OF
130 bool "EHCI support for PPC USB controller on OF platform bus"
131 depends on USB_EHCI_HCD && PPC_OF
134 Enables support for the USB controller present on the PowerPC
135 OpenFirmware platform bus.

139 depends on USB_EHCI_HCD && ARCH_W90X900
141 Enables support for the W90X900 USB controller
143 config USB_OXU210HP_HCD
144 tristate "OXU210HP HCD support"
147 The OXU210HP is an USB host/OTG/device controller. Enable this
148 option if your board has this chip. If unsure, say N.
150 This driver does not support isochronous transfers and doesn't
151 implement OTG nor USB device controllers.
153 To compile this driver as a module, choose M here: the
154 module will be called oxu210hp-hcd.
156 config USB_ISP116X_HCD
157 tristate "ISP116X HCD support"
160 The ISP1160 and ISP1161 chips are USB host controllers. Enable this
161 option if your board has this chip. If unsure, say N.
163 This driver does not support isochronous transfers.

168 config USB_ISP1760_HCD
169 tristate "ISP 1760 HCD support"
170 depends on USB && EXPERIMENTAL
172 The ISP1760 chip is a USB 2.0 host controller.
174 This driver does not support isochronous transfers or OTG.
175 This USB controller is usually attached to a non-DMA-Master
176 capable bus. NXP's eval kit brings this chip on PCI card
177 where the chip itself is behind a PLB to simulate such

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

300 depends on USB && PCI
302 The Universal Host Controller Interface is a standard by Intel for
303 accessing the USB hardware in the PC (which is also called the USB
304 host controller). If your USB host controller conforms to this
305 standard, you may want to say Y, but see below. All recent boards
306 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
307 i810, i820) conform to this standard. Also all VIA PCI chipsets
308 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
309 133). If unsure, say Y.
311 To compile this driver as a module, choose M here: the
312 module will be called uhci-hcd.
315 tristate "Freescale QE USB Host Controller support"
316 depends on USB && OF_GPIO && QE_GPIO && QUICC_ENGINE

321 (as found on MPC8360 and MPC8323 processors), the driver supports
322 Full and Low Speed USB.
325 bool "Freescale QE USB Host Controller debug support"

328 Say "y" to see some FHCI debug information and statistics
332 tristate "Elan U132 Adapter Host Controller"
333 depends on USB && USB_FTDI_ELAN
336 The U132 adapter is a USB to CardBus adapter specifically designed
337 for PC cards that contain an OHCI host controller. Typical PC cards
338 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
339 adapter will *NOT* work with PC cards that do not contain an OHCI
342 For those PC cards that contain multiple OHCI controllers only the
345 The driver consists of two modules, the "ftdi-elan" module is a
346 USB client driver that interfaces to the FTDI chip within ELAN's
347 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
348 controller driver that talks to the OHCI controller within the
349 CardBus cards that are inserted in the U132 adapter.
351 This driver has been tested with a CardBus OHCI USB adapter, and
352 worked with a USB PEN Drive inserted into the first USB port of
353 the PCCARD. A rather pointless thing to do, but useful for testing.
355 It is safe to say M here.
