8 tristate "EHCI HCD (USB 2.0) support"
9 depends on USB && USB_ARCH_HAS_EHCI
11 The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
12 "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
13 If your USB host controller supports USB 2.0, you will likely want to
14 configure this Host Controller Driver. 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.
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
27 You may want to read <file:Documentation/usb/ehci.txt>.
29 To compile this driver as a module, choose M here: the
30 module will be called ehci-hcd.
32 config USB_EHCI_SPLIT_ISO
33 bool "Full speed ISO transactions (EXPERIMENTAL)"
34 depends on USB_EHCI_HCD && EXPERIMENTAL
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.
41 config USB_EHCI_ROOT_HUB_TT
42 bool "Root Hub Transaction Translators (EXPERIMENTAL)"
43 depends on USB_EHCI_HCD && EXPERIMENTAL
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.
50 This supports the EHCI implementation that's originally
51 from ARC, and has since changed hands a few times.
53 config USB_EHCI_TT_NEWSCHED
54 bool "Improved Transaction Translator scheduling (EXPERIMENTAL)"
55 depends on USB_EHCI_HCD && EXPERIMENTAL
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.
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.
70 config USB_ISP116X_HCD
71 tristate "ISP116X HCD support"
74 The ISP1160 and ISP1161 chips are USB host controllers. Enable this
75 option if your board has this chip. If unsure, say N.
77 This driver does not support isochronous transfers.
79 To compile this driver as a module, choose M here: the
80 module will be called isp116x-hcd.
83 tristate "OHCI HCD support"
84 depends on USB && USB_ARCH_HAS_OHCI
85 select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3
87 The Open Host Controller Interface (OHCI) is a standard for accessing
88 USB 1.1 host controller hardware. It does more in hardware than Intel's
89 UHCI specification. If your USB host controller follows the OHCI spec,
90 say Y. On most non-x86 systems, and on x86 hardware that's not using a
91 USB controller from Intel or VIA, this is appropriate. If your host
92 controller doesn't use PCI, this is probably appropriate. For a PCI
93 based system where you're not sure, the "lspci -v" entry will list the
94 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
96 To compile this driver as a module, choose M here: the
97 module will be called ohci-hcd.
99 config USB_OHCI_HCD_PPC_SOC
100 bool "OHCI support for on-chip PPC USB controller"
101 depends on USB_OHCI_HCD && (STB03xxx || PPC_MPC52xx)
103 select USB_OHCI_BIG_ENDIAN
105 Enables support for the USB controller on the MPC52xx or
106 STB03xxx processor chip. If unsure, say Y.
108 config USB_OHCI_HCD_PCI
109 bool "OHCI support for PCI-bus USB controllers"
110 depends on USB_OHCI_HCD && PCI && (STB03xxx || PPC_MPC52xx)
112 select USB_OHCI_LITTLE_ENDIAN
114 Enables support for PCI-bus plug-in USB controller cards.
117 config USB_OHCI_BIG_ENDIAN
119 depends on USB_OHCI_HCD
122 config USB_OHCI_LITTLE_ENDIAN
124 depends on USB_OHCI_HCD
125 default n if STB03xxx || PPC_MPC52xx
129 tristate "UHCI HCD (most Intel and VIA) support"
130 depends on USB && PCI
132 The Universal Host Controller Interface is a standard by Intel for
133 accessing the USB hardware in the PC (which is also called the USB
134 host controller). If your USB host controller conforms to this
135 standard, you may want to say Y, but see below. All recent boards
136 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
137 i810, i820) conform to this standard. Also all VIA PCI chipsets
138 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
139 133). If unsure, say Y.
141 To compile this driver as a module, choose M here: the
142 module will be called uhci-hcd.
145 tristate "SL811HS HCD support"
148 The SL811HS is a single-port USB controller that supports either
149 host side or peripheral side roles. Enable this option if your
150 board has this chip, and you want to use it as a host controller.
153 To compile this driver as a module, choose M here: the
154 module will be called sl811-hcd.
157 tristate "CF/PCMCIA support for SL811HS HCD"
158 depends on USB_SL811_HCD && PCMCIA
160 Wraps a PCMCIA driver around the SL811HS HCD, supporting the RATOC
161 REX-CFU1U CF card (often used with PDAs). If unsure, say N.
163 To compile this driver as a module, choose M here: the
164 module will be called "sl811_cs".
