At the time of this writing, 28 the primary implementation of EHCI is a chip from NEC, widely available 29 in add-on PCI cards, but implementations are in the works from other 30 vendors including Intel and Philips. Motherboard support is appearing. 31 32 EHCI controllers are packaged with "companion" host controllers (OHCI 33 or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports 34 will connect to EHCI if the device is high speed, otherwise they 35 connect to a companion controller. If you configure EHCI, you should 36 probably configure the OHCI (for NEC and some other vendors) USB Host 37 Controller Driver or UHCI (for Via motherboards) Host Controller 38 Driver too. 39 40 You may want to read <file:Documentation/usb/ehci.txt>. 41 42 To compile this driver as a module, choose M here: the 43 module will be called ehci-hcd. 44 45config USB_EHCI_ROOT_HUB_TT 46 bool "Root Hub Transaction Translators" 47 depends on USB_EHCI_HCD 48 ---help--- 49 Some EHCI chips have vendor-specific extensions to integrate 50 transaction translators, so that no OHCI or UHCI companion 51 controller is needed. It's safe to say "y" even if your 52 controller doesn't support this feature. 53 54 This supports the EHCI implementation that's originally 55 from ARC, and has since changed hands a few times. 56 57config USB_EHCI_TT_NEWSCHED 58 bool "Improved Transaction Translator scheduling (EXPERIMENTAL)" 59 depends on USB_EHCI_HCD && EXPERIMENTAL 60 ---help--- 61 This changes the periodic scheduling code to fill more of the low 62 and full speed bandwidth available from the Transaction Translator 63 (TT) in USB 2.0 hubs. Without this, only one transfer will be 64 issued in each microframe, significantly reducing the number of 65 periodic low/fullspeed transfers possible. 66 67 If you have multiple periodic low/fullspeed devices connected to a 68 highspeed USB hub which is connected to a highspeed USB Host 69 Controller, and some of those devices will not work correctly 70 (possibly due to "ENOSPC" or "-28" errors), say Y. 71 72 If unsure, say N. 73 74config USB_EHCI_BIG_ENDIAN_MMIO 75 bool 76 depends on USB_EHCI_HCD && (PPC_CELLEB || PPC_PS3 || 440EPX || ARCH_IXP4XX) 77 default y 78 79config USB_EHCI_BIG_ENDIAN_DESC 80 bool 81 depends on USB_EHCI_HCD && (440EPX || ARCH_IXP4XX) 82 default y 83 84config USB_EHCI_FSL 85 bool "Support for Freescale on-chip EHCI USB controller" 86 depends on USB_EHCI_HCD && FSL_SOC 87 select USB_EHCI_ROOT_HUB_TT 88 ---help--- 89 Variation of ARC USB block used in some Freescale chips. 90 91config USB_EHCI_HCD_PPC_OF 92 bool "EHCI support for PPC USB controller on OF platform bus" 93 depends on USB_EHCI_HCD && PPC_OF 94 default y 95 ---help--- 96 Enables support for the USB controller present on the PowerPC 97 OpenFirmware platform bus. 98 99config USB_ISP116X_HCD 100 tristate "ISP116X HCD support" 101 depends on USB 102 ---help--- 103 The ISP1160 and ISP1161 chips are USB host controllers.

On most non-x86 systems, and on x86 hardware that's not using a 147 USB controller from Intel or VIA, this is appropriate. If your host 148 controller doesn't use PCI, this is probably appropriate. For a PCI 149 based system where you're not sure, the "lspci -v" entry will list the 150 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI. 151 152 To compile this driver as a module, choose M here: the 153 module will be called ohci-hcd. 154 155config USB_OHCI_HCD_PPC_SOC 156 bool "OHCI support for on-chip PPC USB controller" 157 depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx) 158 default y 159 select USB_OHCI_BIG_ENDIAN_DESC 160 select USB_OHCI_BIG_ENDIAN_MMIO 161 ---help--- 162 Enables support for the USB controller on the MPC52xx or 163 STB03xxx processor chip.

If your USB host controller conforms to this 231 standard, you may want to say Y, but see below. All recent boards 232 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, 233 i810, i820) conform to this standard.

Typical PC cards 247 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132 248 adapter will *NOT* work with PC cards that do not contain an OHCI 249 controller. 250 251 For those PC cards that contain multiple OHCI controllers only the 252 first one is used. 253 254 The driver consists of two modules, the "ftdi-elan" module is a 255 USB client driver that interfaces to the FTDI chip within ELAN's 256 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host 257 controller driver that talks to the OHCI controller within the 258 CardBus cards that are inserted in the U132 adapter. 259 260 This driver has been tested with a CardBus OHCI USB adapter, and 261 worked with a USB PEN Drive inserted into the first USB port of 262 the PCCARD. A rather pointless thing to do, but useful for testing. 263 264 It is safe to say M here. 265 266 See also <http://www.elandigitalsystems.com/support/ufaq/u132linux.php> 267 268config USB_SL811_HCD 269 tristate "SL811HS HCD support" 270 depends on USB 271 help 272 The SL811HS is a single-port USB controller that supports either 273 host side or peripheral side roles.
