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

148 Enables support for the W90X900 USB controller
150 config USB_OXU210HP_HCD
151 tristate "OXU210HP HCD support"
154 The OXU210HP is an USB host/OTG/device controller. Enable this
155 option if your board has this chip. If unsure, say N.
157 This driver does not support isochronous transfers and doesn't
158 implement OTG nor USB device controllers.

161 module will be called oxu210hp-hcd.

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

195 Supports the Philips ISP1362 chip as a host controller
197 This driver does not support isochronous transfers.
199 To compile this driver as a module, choose M here: the
200 module will be called isp1362-hcd.

205 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
206 select USB_OTG_UTILS if ARCH_OMAP
208 The Open Host Controller Interface (OHCI) is a standard for accessing
209 USB 1.1 host controller hardware. It does more in hardware than Intel's
210 UHCI specification. If your USB host controller follows the OHCI spec,
211 say Y. On most non-x86 systems, and on x86 hardware that's not using a
212 USB controller from Intel or VIA, this is appropriate. If your host
213 controller doesn't use PCI, this is probably appropriate. For a PCI
214 based system where you're not sure, the "lspci -v" entry will list the
215 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.

218 module will be called ohci-hcd.

307 depends on USB && PCI
309 The Universal Host Controller Interface is a standard by Intel for
310 accessing the USB hardware in the PC (which is also called the USB
311 host controller). If your USB host controller conforms to this
312 standard, you may want to say Y, but see below. All recent boards
313 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
314 i810, i820) conform to this standard. Also all VIA PCI chipsets
315 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
316 133). If unsure, say Y.

319 module will be called uhci-hcd.

329 Full and Low Speed USB.

339 tristate "Elan U132 Adapter Host Controller"
340 depends on USB && USB_FTDI_ELAN
343 The U132 adapter is a USB to CardBus adapter specifically designed
344 for PC cards that contain an OHCI host controller. Typical PC cards
345 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
346 adapter will *NOT* work with PC cards that do not contain an OHCI

352 The driver consists of two modules, the "ftdi-elan" module is a
353 USB client driver that interfaces to the FTDI chip within ELAN's
354 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
355 controller driver that talks to the OHCI controller within the
356 CardBus cards that are inserted in the U132 adapter.
358 This driver has been tested with a CardBus OHCI USB adapter, and
359 worked with a USB PEN Drive inserted into the first USB port of
360 the PCCARD. A rather pointless thing to do, but useful for testing.
362 It is safe to say M here.
