At the time of this writing, 15 the primary implementation of EHCI is a chip from NEC, widely available 16 in add-on PCI cards, but implementations are in the works from other 17 vendors including Intel and Philips. Motherboard support is appearing. 18 19 EHCI controllers are packaged with "companion" host controllers (OHCI 20 or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports 21 will connect to EHCI if the device is high speed, otherwise they 22 connect to a companion controller. If you configure EHCI, you should 23 probably configure the OHCI (for NEC and some other vendors) USB Host 24 Controller Driver or UHCI (for Via motherboards) Host Controller 25 Driver too. 26 27 You may want to read <file:Documentation/usb/ehci.txt>. 28 29 To compile this driver as a module, choose M here: the 30 module will be called ehci-hcd. 31 32config USB_EHCI_SPLIT_ISO 33 bool "Full speed ISO transactions (EXPERIMENTAL)" 34 depends on USB_EHCI_HCD && EXPERIMENTAL 35 default n 36 ---help--- 37 This code is new and hasn't been used with many different 38 EHCI or USB 2.0 transaction translator implementations. 39 It should work for ISO-OUT transfers, like audio. 40 41config USB_EHCI_ROOT_HUB_TT 42 bool "Root Hub Transaction Translators (EXPERIMENTAL)" 43 depends on USB_EHCI_HCD && EXPERIMENTAL 44 ---help--- 45 Some EHCI chips have vendor-specific extensions to integrate 46 transaction translators, so that no OHCI or UHCI companion 47 controller is needed. It's safe to say "y" even if your 48 controller doesn't support this feature. 49 50 This supports the EHCI implementation from TransDimension Inc. 51 52config USB_ISP116X_HCD 53 tristate "ISP116X HCD support" 54 depends on USB 55 default N 56 ---help--- 57 The ISP1160 and ISP1161 chips are USB host controllers. Enable this 58 option if your board has this chip. If unsure, say N. 59 60 This driver does not support isochronous transfers. 61 62 To compile this driver as a module, choose M here: the 63 module will be called isp116x-hcd. 64 65config USB_OHCI_HCD 66 tristate "OHCI HCD support" 67 depends on USB && USB_ARCH_HAS_OHCI 68 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3 69 ---help--- 70 The Open Host Controller Interface (OHCI) is a standard for accessing 71 USB 1.1 host controller hardware. It does more in hardware than Intel's 72 UHCI specification. If your USB host controller follows the OHCI spec, 73 say Y. On most non-x86 systems, and on x86 hardware that's not using a 74 USB controller from Intel or VIA, this is appropriate. If your host 75 controller doesn't use PCI, this is probably appropriate. For a PCI 76 based system where you're not sure, the "lspci -v" entry will list the 77 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI. 78 79 To compile this driver as a module, choose M here: the 80 module will be called ohci-hcd. 81 82config USB_OHCI_HCD_PPC_SOC 83 bool "OHCI support for on-chip PPC USB controller" 84 depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx) 85 default y 86 select USB_OHCI_BIG_ENDIAN 87 ---help--- 88 Enables support for the USB controller on the MPC52xx or 89 STB03xxx processor chip.

If your USB host controller conforms to this 118 standard, you may want to say Y, but see below. All recent boards 119 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, 120 i810, i820) conform to this standard. Also all VIA PCI chipsets 121 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro 122 133). If unsure, say Y. 123 124 To compile this driver as a module, choose M here: the 125 module will be called uhci-hcd. 126 127config USB_SL811_HCD 128 tristate "SL811HS HCD support" 129 depends on USB 130 default N 131 help 132 The SL811HS is a single-port USB controller that supports either 133 host side or peripheral side roles. Enable this option if your 134 board has this chip, and you want to use it as a host controller. 135 If unsure, say N. 136 137 To compile this driver as a module, choose M here: the 138 module will be called sl811-hcd. 139 140config USB_SL811_CS 141 tristate "CF/PCMCIA support for SL811HS HCD" 142 depends on USB_SL811_HCD && PCMCIA 143 default N 144 help 145 Wraps a PCMCIA driver around the SL811HS HCD, supporting the RATOC 146 REX-CFU1U CF card (often used with PDAs).
