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

177 config USB_OXU210HP_HCD
178 tristate "OXU210HP HCD support"
181 The OXU210HP is an USB host/OTG/device controller. Enable this
182 option if your board has this chip. If unsure, say N.
184 This driver does not support isochronous transfers and doesn't
185 implement OTG nor USB device controllers.

188 module will be called oxu210hp-hcd.

194 The ISP1160 and ISP1161 chips are USB host controllers. Enable this
195 option if your board has this chip. If unsure, say N.

233 select USB_OTG_UTILS if ARCH_OMAP
235 The Open Host Controller Interface (OHCI) is a standard for accessing
236 USB 1.1 host controller hardware. It does more in hardware than Intel's
237 UHCI specification. If your USB host controller follows the OHCI spec,
238 say Y. On most non-x86 systems, and on x86 hardware that's not using a
239 USB controller from Intel or VIA, this is appropriate. If your host
240 controller doesn't use PCI, this is probably appropriate. For a PCI
241 based system where you're not sure, the "lspci -v" entry will list the
242 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
244 To compile this driver as a module, choose M here: the
245 module will be called ohci-hcd.

343 The Universal Host Controller Interface is a standard by Intel for
344 accessing the USB hardware in the PC (which is also called the USB
345 host controller). If your USB host controller conforms to this
346 standard, you may want to say Y, but see below. All recent boards
347 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
348 i810, i820) conform to this standard. Also all VIA PCI chipsets
349 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
350 133). If unsure, say Y.

377 The U132 adapter is a USB to CardBus adapter specifically designed
378 for PC cards that contain an OHCI host controller. Typical PC cards
379 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132

387 USB client driver that interfaces to the FTDI chip within ELAN's
388 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
389 controller driver that talks to the OHCI controller within the
390 CardBus cards that are inserted in the U132 adapter.
392 This driver has been tested with a CardBus OHCI USB adapter, and
393 worked with a USB PEN Drive inserted into the first USB port of
394 the PCCARD. A rather pointless thing to do, but useful for testing.
