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 && (PPC_CELLEB || PPC_PS3 || 440EPX) 73 default y 74 75config USB_EHCI_BIG_ENDIAN_DESC 76 bool 77 depends on USB_EHCI_HCD && 440EPX 78 default y 79 80config USB_EHCI_FSL 81 bool 82 select USB_EHCI_ROOT_HUB_TT 83 default y if MPC834x || PPC_MPC831x 84 ---help--- 85 Variation of ARC USB block used in some Freescale chips. 86 87config USB_ISP116X_HCD 88 tristate "ISP116X HCD support" 89 depends on USB 90 ---help--- 91 The ISP1160 and ISP1161 chips are USB host controllers.

It does more in hardware than Intel's 107 UHCI specification. If your USB host controller follows the OHCI spec, 108 say Y. On most non-x86 systems, and on x86 hardware that's not using a 109 USB controller from Intel or VIA, this is appropriate. If your host 110 controller doesn't use PCI, this is probably appropriate. For a PCI 111 based system where you're not sure, the "lspci -v" entry will list the 112 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI. 113 114 To compile this driver as a module, choose M here: the 115 module will be called ohci-hcd. 116 117config USB_OHCI_HCD_PPC_SOC 118 bool "OHCI support for on-chip PPC USB controller" 119 depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx) 120 default y 121 select USB_OHCI_BIG_ENDIAN_DESC 122 select USB_OHCI_BIG_ENDIAN_MMIO 123 ---help--- 124 Enables support for the USB controller on the MPC52xx or 125 STB03xxx processor chip.

If your USB host controller conforms to this 193 standard, you may want to say Y, but see below. All recent boards 194 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, 195 i810, i820) conform to this standard.

Typical PC cards 209 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132 210 adapter will *NOT* work with PC cards that do not contain an OHCI 211 controller. 212 213 For those PC cards that contain multiple OHCI controllers only the 214 first one is used. 215 216 The driver consists of two modules, the "ftdi-elan" module is a 217 USB client driver that interfaces to the FTDI chip within ELAN's 218 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host 219 controller driver that talks to the OHCI controller within the 220 CardBus cards that are inserted in the U132 adapter. 221 222 This driver has been tested with a CardBus OHCI USB adapter, and 223 worked with a USB PEN Drive inserted into the first USB port of 224 the PCCARD. A rather pointless thing to do, but useful for testing. 225 226 It is safe to say M here. 227 228 See also <http://www.elandigitalsystems.com/support/ufaq/u132linux.php> 229 230config USB_SL811_HCD 231 tristate "SL811HS HCD support" 232 depends on USB 233 help 234 The SL811HS is a single-port USB controller that supports either 235 host side or peripheral side roles.
