If your USB host controller conforms to this 612 standard, you may want to say Y, but see below. All recent boards 613 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, 614 i810, i820) conform to this standard. Also all VIA PCI chipsets 615 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro 616 133) and LEON/GRLIB SoCs with the GRUSBHC controller. 617 If unsure, say Y. 618 619 To compile this driver as a module, choose M here: the 620 module will be called uhci-hcd. 621 622config USB_UHCI_SUPPORT_NON_PCI_HC 623 bool 624 default y if (SPARC_LEON || USB_UHCI_PLATFORM) 625 626config USB_UHCI_PLATFORM 627 bool 628 default y if (ARCH_VT8500 || ARCH_ASPEED) 629 630config USB_UHCI_ASPEED 631 bool 632 default y if ARCH_ASPEED 633 634config USB_FHCI_HCD 635 tristate "Freescale QE USB Host Controller support" 636 depends on OF_GPIO && QE_GPIO && QUICC_ENGINE 637 select FSL_GTM 638 select QE_USB 639 help 640 This driver enables support for Freescale QE USB Host Controller 641 (as found on MPC8360 and MPC8323 processors), the driver supports 642 Full and Low Speed USB. 643 644config FHCI_DEBUG 645 bool "Freescale QE USB Host Controller debug support" 646 depends on USB_FHCI_HCD && DEBUG_FS 647 help 648 Say "y" to see some FHCI debug information and statistics 649 through debugfs. 650 651config USB_U132_HCD 652 tristate "Elan U132 Adapter Host Controller" 653 depends on USB_FTDI_ELAN 654 help 655 The U132 adapter is a USB to CardBus adapter specifically designed 656 for PC cards that contain an OHCI host controller. Typical PC cards 657 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132 658 adapter will *NOT* work with PC cards that do not contain an OHCI 659 controller. 660 661 For those PC cards that contain multiple OHCI controllers only the 662 first one is used. 663 664 The driver consists of two modules, the "ftdi-elan" module is a 665 USB client driver that interfaces to the FTDI chip within ELAN's 666 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host 667 controller driver that talks to the OHCI controller within the 668 CardBus cards that are inserted in the U132 adapter. 669 670 This driver has been tested with a CardBus OHCI USB adapter, and 671 worked with a USB PEN Drive inserted into the first USB port of 672 the PCCARD. A rather pointless thing to do, but useful for testing. 673 674 It is safe to say M here. 675 676 See also <http://www.elandigitalsystems.com/support/ufaq/u132linux.php> 677 678config USB_SL811_HCD 679 tristate "SL811HS HCD support" 680 depends on HAS_IOMEM 681 help 682 The SL811HS is a single-port USB controller that supports either 683 host side or peripheral side roles.

Typically this will be enabled for On-the-Go 767 or embedded hosts that need to undergo USB-IF compliance testing with 768 the aid of special testing hardware. In the future, this may expand 769 to include other tests that require support from a HCD driver. 770 771 This option is of interest only to developers who need to validate 772 their USB hardware designs.
