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 that's originally 51 from ARC, and has since changed hands a few times. 52 53config USB_EHCI_TT_NEWSCHED 54 bool "Improved Transaction Translator scheduling (EXPERIMENTAL)" 55 depends on USB_EHCI_HCD && EXPERIMENTAL 56 ---help--- 57 This changes the periodic scheduling code to fill more of the low 58 and full speed bandwidth available from the Transaction Translator 59 (TT) in USB 2.0 hubs. Without this, only one transfer will be 60 issued in each microframe, significantly reducing the number of 61 periodic low/fullspeed transfers possible. 62 63 If you have multiple periodic low/fullspeed devices connected to a 64 highspeed USB hub which is connected to a highspeed USB Host 65 Controller, and some of those devices will not work correctly 66 (possibly due to "ENOSPC" or "-28" errors), say Y. 67 68 If unsure, say N. 69 70config USB_EHCI_BIG_ENDIAN_MMIO 71 bool 72 depends on USB_EHCI_HCD 73 default n 74 75config USB_ISP116X_HCD 76 tristate "ISP116X HCD support" 77 depends on USB 78 ---help--- 79 The ISP1160 and ISP1161 chips are USB host controllers. Enable this 80 option if your board has this chip. If unsure, say N. 81 82 This driver does not support isochronous transfers. 83 84 To compile this driver as a module, choose M here: the 85 module will be called isp116x-hcd. 86 87config USB_OHCI_HCD 88 tristate "OHCI HCD support" 89 depends on USB && USB_ARCH_HAS_OHCI 90 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3 91 select I2C if ARCH_PNX4008 92 ---help--- 93 The Open Host Controller Interface (OHCI) is a standard for accessing 94 USB 1.1 host controller hardware. It does more in hardware than Intel's 95 UHCI specification. If your USB host controller follows the OHCI spec, 96 say Y. On most non-x86 systems, and on x86 hardware that's not using a 97 USB controller from Intel or VIA, this is appropriate. If your host 98 controller doesn't use PCI, this is probably appropriate. For a PCI 99 based system where you're not sure, the "lspci -v" entry will list the 100 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI. 101 102 To compile this driver as a module, choose M here: the 103 module will be called ohci-hcd. 104 105config USB_OHCI_HCD_PPC_SOC 106 bool "OHCI support for on-chip PPC USB controller" 107 depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx) 108 default y 109 select USB_OHCI_BIG_ENDIAN_DESC 110 select USB_OHCI_BIG_ENDIAN_MMIO 111 ---help--- 112 Enables support for the USB controller on the MPC52xx or 113 STB03xxx processor chip.

If your USB host controller conforms to this 168 standard, you may want to say Y, but see below. All recent boards 169 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, 170 i810, i820) conform to this standard. Also all VIA PCI chipsets 171 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro 172 133). If unsure, say Y. 173 174 To compile this driver as a module, choose M here: the 175 module will be called uhci-hcd. 176 177config USB_U132_HCD 178 tristate "Elan U132 Adapter Host Controller" 179 depends on USB && USB_FTDI_ELAN 180 default M 181 help 182 The U132 adapter is a USB to CardBus adapter specifically designed 183 for PC cards that contain an OHCI host controller. Typical PC cards 184 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132 185 adapter will *NOT* work with PC cards that do not contain an OHCI 186 controller. 187 188 For those PC cards that contain multiple OHCI controllers only the 189 first one is used. 190 191 The driver consists of two modules, the "ftdi-elan" module is a 192 USB client driver that interfaces to the FTDI chip within ELAN's 193 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host 194 controller driver that talks to the OHCI controller within the 195 CardBus cards that are inserted in the U132 adapter. 196 197 This driver has been tested with a CardBus OHCI USB adapter, and 198 worked with a USB PEN Drive inserted into the first USB port of 199 the PCCARD. A rather pointless thing to do, but useful for testing. 200 201 It is safe to say M here. 202 203 See also <http://www.elandigitalsystems.com/support/ufaq/u132linux.php> 204 205config USB_SL811_HCD 206 tristate "SL811HS HCD support" 207 depends on USB 208 help 209 The SL811HS is a single-port USB controller that supports either 210 host side or peripheral side roles. Enable this option if your 211 board has this chip, and you want to use it as a host controller. 212 If unsure, say N. 213 214 To compile this driver as a module, choose M here: the 215 module will be called sl811-hcd. 216 217config USB_SL811_CS 218 tristate "CF/PCMCIA support for SL811HS HCD" 219 depends on USB_SL811_HCD && PCMCIA 220 help 221 Wraps a PCMCIA driver around the SL811HS HCD, supporting the RATOC 222 REX-CFU1U CF card (often used with PDAs).
