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

263 The Open Host Controller Interface (OHCI) is a standard for accessing
264 USB 1.1 host controller hardware. It does more in hardware than Intel's
265 UHCI specification. If your USB host controller follows the OHCI spec,
266 say Y. On most non-x86 systems, and on x86 hardware that's not using a
267 USB controller from Intel or VIA, this is appropriate. If your host
268 controller doesn't use PCI, this is probably appropriate. For a PCI
269 based system where you're not sure, the "lspci -v" entry will list the
270 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.

378 The Universal Host Controller Interface is a standard by Intel for
379 accessing the USB hardware in the PC (which is also called the USB
380 host controller). If your USB host controller conforms to this
381 standard, you may want to say Y, but see below. All recent boards
382 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
383 i810, i820) conform to this standard. Also all VIA PCI chipsets

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