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_ROOT_HUB_TT 33 bool "Root Hub Transaction Translators (EXPERIMENTAL)" 34 depends on USB_EHCI_HCD && EXPERIMENTAL 35 ---help--- 36 Some EHCI chips have vendor-specific extensions to integrate 37 transaction translators, so that no OHCI or UHCI companion 38 controller is needed. It's safe to say "y" even if your 39 controller doesn't support this feature. 40 41 This supports the EHCI implementation that's originally 42 from ARC, and has since changed hands a few times. 43 44config USB_EHCI_TT_NEWSCHED 45 bool "Improved Transaction Translator scheduling (EXPERIMENTAL)" 46 depends on USB_EHCI_HCD && EXPERIMENTAL 47 ---help--- 48 This changes the periodic scheduling code to fill more of the low 49 and full speed bandwidth available from the Transaction Translator 50 (TT) in USB 2.0 hubs. Without this, only one transfer will be 51 issued in each microframe, significantly reducing the number of 52 periodic low/fullspeed transfers possible. 53 54 If you have multiple periodic low/fullspeed devices connected to a 55 highspeed USB hub which is connected to a highspeed USB Host 56 Controller, and some of those devices will not work correctly 57 (possibly due to "ENOSPC" or "-28" errors), say Y. 58 59 If unsure, say N. 60 61config USB_EHCI_BIG_ENDIAN_MMIO 62 bool 63 depends on USB_EHCI_HCD && (PPC_CELLEB || PPC_PS3 || 440EPX || ARCH_IXP4XX) 64 default y 65 66config USB_EHCI_BIG_ENDIAN_DESC 67 bool 68 depends on USB_EHCI_HCD && (440EPX || ARCH_IXP4XX) 69 default y 70 71config USB_EHCI_FSL 72 bool "Support for Freescale on-chip EHCI USB controller" 73 depends on USB_EHCI_HCD && FSL_SOC 74 select USB_EHCI_ROOT_HUB_TT 75 ---help--- 76 Variation of ARC USB block used in some Freescale chips. 77 78config USB_EHCI_HCD_PPC_OF 79 bool "EHCI support for PPC USB controller on OF platform bus" 80 depends on USB_EHCI_HCD && PPC_OF 81 default y 82 ---help--- 83 Enables support for the USB controller present on the PowerPC 84 OpenFirmware platform bus. 85 86config USB_ISP116X_HCD 87 tristate "ISP116X HCD support" 88 depends on USB 89 ---help--- 90 The ISP1160 and ISP1161 chips are USB host controllers.

It does more in hardware than Intel's 106 UHCI specification. If your USB host controller follows the OHCI spec, 107 say Y. On most non-x86 systems, and on x86 hardware that's not using a 108 USB controller from Intel or VIA, this is appropriate. If your host 109 controller doesn't use PCI, this is probably appropriate. For a PCI 110 based system where you're not sure, the "lspci -v" entry will list the 111 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI. 112 113 To compile this driver as a module, choose M here: the 114 module will be called ohci-hcd. 115 116config USB_OHCI_HCD_PPC_SOC 117 bool "OHCI support for on-chip PPC USB controller" 118 depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx) 119 default y 120 select USB_OHCI_BIG_ENDIAN_DESC 121 select USB_OHCI_BIG_ENDIAN_MMIO 122 ---help--- 123 Enables support for the USB controller on the MPC52xx or 124 STB03xxx processor chip.

If your USB host controller conforms to this 192 standard, you may want to say Y, but see below. All recent boards 193 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, 194 i810, i820) conform to this standard.

Typical PC cards 208 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132 209 adapter will *NOT* work with PC cards that do not contain an OHCI 210 controller. 211 212 For those PC cards that contain multiple OHCI controllers only the 213 first one is used. 214 215 The driver consists of two modules, the "ftdi-elan" module is a 216 USB client driver that interfaces to the FTDI chip within ELAN's 217 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host 218 controller driver that talks to the OHCI controller within the 219 CardBus cards that are inserted in the U132 adapter. 220 221 This driver has been tested with a CardBus OHCI USB adapter, and 222 worked with a USB PEN Drive inserted into the first USB port of 223 the PCCARD. A rather pointless thing to do, but useful for testing. 224 225 It is safe to say M here. 226 227 See also <http://www.elandigitalsystems.com/support/ufaq/u132linux.php> 228 229config USB_SL811_HCD 230 tristate "SL811HS HCD support" 231 depends on USB 232 help 233 The SL811HS is a single-port USB controller that supports either 234 host side or peripheral side roles.
