# # USB Host Controller Drivers # comment "USB Host Controller Drivers" depends on USB config USB_C67X00_HCD tristate "Cypress C67x00 HCD support" depends on USB help The Cypress C67x00 (EZ-Host/EZ-OTG) chips are dual-role host/peripheral/OTG USB controllers. Enable this option to support this chip in host controller mode. If unsure, say N. To compile this driver as a module, choose M here: the module will be called c67x00. config USB_XHCI_HCD tristate "xHCI HCD (USB 3.0) support (EXPERIMENTAL)" depends on USB && PCI && EXPERIMENTAL ---help--- The eXtensible Host Controller Interface (xHCI) is standard for USB 3.0 "SuperSpeed" host controller hardware. To compile this driver as a module, choose M here: the module will be called xhci-hcd. config USB_XHCI_HCD_DEBUGGING bool "Debugging for the xHCI host controller" depends on USB_XHCI_HCD ---help--- Say 'Y' to turn on debugging for the xHCI host controller driver. This will spew debugging output, even in interrupt context. This should only be used for debugging xHCI driver bugs. If unsure, say N. config USB_EHCI_HCD tristate "EHCI HCD (USB 2.0) support" depends on USB && USB_ARCH_HAS_EHCI ---help--- The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0 "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware. If your USB host controller supports USB 2.0, you will likely want to configure this Host Controller Driver. EHCI controllers are packaged with "companion" host controllers (OHCI or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports will connect to EHCI if the device is high speed, otherwise they connect to a companion controller. If you configure EHCI, you should probably configure the OHCI (for NEC and some other vendors) USB Host Controller Driver or UHCI (for Via motherboards) Host Controller Driver too. You may want to read . To compile this driver as a module, choose M here: the module will be called ehci-hcd. config USB_EHCI_ROOT_HUB_TT bool "Root Hub Transaction Translators" depends on USB_EHCI_HCD ---help--- Some EHCI chips have vendor-specific extensions to integrate transaction translators, so that no OHCI or UHCI companion controller is needed. It's safe to say "y" even if your controller doesn't support this feature. This supports the EHCI implementation that's originally from ARC, and has since changed hands a few times. config USB_EHCI_TT_NEWSCHED bool "Improved Transaction Translator scheduling (EXPERIMENTAL)" depends on USB_EHCI_HCD && EXPERIMENTAL ---help--- This changes the periodic scheduling code to fill more of the low and full speed bandwidth available from the Transaction Translator (TT) in USB 2.0 hubs. Without this, only one transfer will be issued in each microframe, significantly reducing the number of periodic low/fullspeed transfers possible. If you have multiple periodic low/fullspeed devices connected to a highspeed USB hub which is connected to a highspeed USB Host Controller, and some of those devices will not work correctly (possibly due to "ENOSPC" or "-28" errors), say Y. If unsure, say N. config USB_EHCI_BIG_ENDIAN_MMIO bool depends on USB_EHCI_HCD && (PPC_CELLEB || PPC_PS3 || 440EPX || ARCH_IXP4XX) default y config USB_EHCI_BIG_ENDIAN_DESC bool depends on USB_EHCI_HCD && (440EPX || ARCH_IXP4XX) default y config USB_EHCI_FSL bool "Support for Freescale on-chip EHCI USB controller" depends on USB_EHCI_HCD && FSL_SOC select USB_EHCI_ROOT_HUB_TT ---help--- Variation of ARC USB block used in some Freescale chips. config USB_EHCI_HCD_PPC_OF bool "EHCI support for PPC USB controller on OF platform bus" depends on USB_EHCI_HCD && PPC_OF default y ---help--- Enables support for the USB controller present on the PowerPC OpenFirmware platform bus. config USB_W90X900_EHCI bool "W90X900(W90P910) EHCI support" depends on USB_EHCI_HCD && ARCH_W90X900 ---help--- Enables support for the W90X900 USB controller config USB_OXU210HP_HCD tristate "OXU210HP HCD support" depends on USB ---help--- The OXU210HP is an USB host/OTG/device controller. Enable this option if your board has this chip. If unsure, say N. This driver does not support isochronous transfers and doesn't implement OTG nor USB device controllers. To compile this driver as a module, choose M here: the module will be called oxu210hp-hcd. config USB_ISP116X_HCD tristate "ISP116X HCD support" depends on USB ---help--- The ISP1160 and ISP1161 chips are USB host controllers. Enable this option if your board has this chip. If unsure, say N. This driver does not support isochronous transfers. To compile this driver as a module, choose M here: the module will be called isp116x-hcd. config USB_ISP1760_HCD tristate "ISP 1760 HCD support" depends on USB && EXPERIMENTAL ---help--- The ISP1760 chip is a USB 2.0 host controller. This driver does not support isochronous transfers or OTG. This USB controller is usually attached to a non-DMA-Master capable bus. NXP's eval kit brings this chip on PCI card where the chip itself is behind a PLB to simulate such a bus. To compile this driver as a module, choose M here: the module will be called isp1760. config USB_OHCI_HCD tristate "OHCI HCD support" depends on USB && USB_ARCH_HAS_OHCI select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3 select USB_OTG_UTILS if ARCH_OMAP ---help--- The Open Host Controller Interface (OHCI) is a standard for accessing USB 1.1 host controller hardware. It does more in hardware than Intel's UHCI specification. If your USB host controller follows the OHCI spec, say Y. On most non-x86 systems, and on x86 hardware that's not using a USB controller from Intel or VIA, this is appropriate. If your host controller doesn't use PCI, this is probably appropriate. For a PCI based system where you're not sure, the "lspci -v" entry will list the right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI. To compile this driver as a module, choose M here: the module will be called ohci-hcd. config USB_OHCI_HCD_PPC_SOC bool "OHCI support for on-chip PPC USB controller" depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx) default y select USB_OHCI_BIG_ENDIAN_DESC select USB_OHCI_BIG_ENDIAN_MMIO ---help--- Enables support for the USB controller on the MPC52xx or STB03xxx processor chip.

If unsure, say Y. config USB_OHCI_HCD_SSB bool "OHCI support for Broadcom SSB OHCI core" depends on USB_OHCI_HCD && (SSB = y || SSB = USB_OHCI_HCD) && EXPERIMENTAL default n ---help--- Support for the Sonics Silicon Backplane (SSB) attached Broadcom USB OHCI core. This device is present in some embedded devices with Broadcom based SSB bus. If unsure, say N. config USB_OHCI_BIG_ENDIAN_DESC bool depends on USB_OHCI_HCD default n config USB_OHCI_BIG_ENDIAN_MMIO bool depends on USB_OHCI_HCD default n config USB_OHCI_LITTLE_ENDIAN bool depends on USB_OHCI_HCD default n if STB03xxx || PPC_MPC52xx default y config USB_UHCI_HCD tristate "UHCI HCD (most Intel and VIA) support" depends on USB && PCI ---help--- The Universal Host Controller Interface is a standard by Intel for accessing the USB hardware in the PC (which is also called the USB host controller). If your USB host controller conforms to this standard, you may want to say Y, but see below. All recent boards with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, i810, i820) conform to this standard. Also all VIA PCI chipsets (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro 133). If unsure, say Y. To compile this driver as a module, choose M here: the module will be called uhci-hcd. config USB_FHCI_HCD tristate "Freescale QE USB Host Controller support" depends on USB && OF_GPIO && QE_GPIO && QUICC_ENGINE select FSL_GTM select QE_USB help This driver enables support for Freescale QE USB Host Controller (as found on MPC8360 and MPC8323 processors), the driver supports Full and Low Speed USB. config FHCI_DEBUG bool "Freescale QE USB Host Controller debug support" depends on USB_FHCI_HCD && DEBUG_FS help Say "y" to see some FHCI debug information and statistics throught debugfs. config USB_U132_HCD tristate "Elan U132 Adapter Host Controller" depends on USB && USB_FTDI_ELAN default M help The U132 adapter is a USB to CardBus adapter specifically designed for PC cards that contain an OHCI host controller. Typical PC cards are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132 adapter will *NOT* work with PC cards that do not contain an OHCI controller. For those PC cards that contain multiple OHCI controllers only the first one is used. The driver consists of two modules, the "ftdi-elan" module is a USB client driver that interfaces to the FTDI chip within ELAN's USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host controller driver that talks to the OHCI controller within the CardBus cards that are inserted in the U132 adapter. This driver has been tested with a CardBus OHCI USB adapter, and worked with a USB PEN Drive inserted into the first USB port of the PCCARD. A rather pointless thing to do, but useful for testing. It is safe to say M here. See also config USB_SL811_HCD tristate "SL811HS HCD support" depends on USB help The SL811HS is a single-port USB controller that supports either host side or peripheral side roles.
