If your USB host controller conforms to this 613 standard, you may want to say Y, but see below. All recent boards 614 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, 615 i810, i820) conform to this standard. Also all VIA PCI chipsets 616 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro 617 133) and LEON/GRLIB SoCs with the GRUSBHC controller. 618 If unsure, say Y. 619 620 To compile this driver as a module, choose M here: the 621 module will be called uhci-hcd. 622 623config USB_UHCI_SUPPORT_NON_PCI_HC 624 bool 625 default y if (SPARC_LEON || USB_UHCI_PLATFORM) 626 627config USB_UHCI_PLATFORM 628 bool 629 default y if (ARCH_VT8500 || ARCH_ASPEED) 630 631config USB_UHCI_ASPEED 632 bool 633 default y if ARCH_ASPEED 634 635config USB_FHCI_HCD 636 tristate "Freescale QE USB Host Controller support" 637 depends on OF_GPIO && QE_GPIO && QUICC_ENGINE 638 select FSL_GTM 639 select QE_USB 640 help 641 This driver enables support for Freescale QE USB Host Controller 642 (as found on MPC8360 and MPC8323 processors), the driver supports 643 Full and Low Speed USB. 644 645config FHCI_DEBUG 646 bool "Freescale QE USB Host Controller debug support" 647 depends on USB_FHCI_HCD && DEBUG_FS 648 help 649 Say "y" to see some FHCI debug information and statistics 650 through debugfs. 651 652config USB_U132_HCD 653 tristate "Elan U132 Adapter Host Controller" 654 depends on USB_FTDI_ELAN 655 help 656 The U132 adapter is a USB to CardBus adapter specifically designed 657 for PC cards that contain an OHCI host controller. Typical PC cards 658 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132 659 adapter will *NOT* work with PC cards that do not contain an OHCI 660 controller. 661 662 For those PC cards that contain multiple OHCI controllers only the 663 first one is used. 664 665 The driver consists of two modules, the "ftdi-elan" module is a 666 USB client driver that interfaces to the FTDI chip within ELAN's 667 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host 668 controller driver that talks to the OHCI controller within the 669 CardBus cards that are inserted in the U132 adapter. 670 671 This driver has been tested with a CardBus OHCI USB adapter, and 672 worked with a USB PEN Drive inserted into the first USB port of 673 the PCCARD. A rather pointless thing to do, but useful for testing. 674 675 It is safe to say M here. 676 677 See also <http://www.elandigitalsystems.com/support/ufaq/u132linux.php> 678 679config USB_SL811_HCD 680 tristate "SL811HS HCD support" 681 depends on HAS_IOMEM 682 help 683 The SL811HS is a single-port USB controller that supports either 684 host side or peripheral side roles.

Typically this will be enabled for On-the-Go 768 or embedded hosts that need to undergo USB-IF compliance testing with 769 the aid of special testing hardware. In the future, this may expand 770 to include other tests that require support from a HCD driver. 771 772 This option is of interest only to developers who need to validate 773 their USB hardware designs.
