8 tristate "Cypress C67x00 HCD support"
11 The Cypress C67x00 (EZ-Host/EZ-OTG) chips are dual-role
12 host/peripheral/OTG USB controllers.
14 Enable this option to support this chip in host controller mode.
17 To compile this driver as a module, choose M here: the
18 module will be called c67x00.
21 tristate "xHCI HCD (USB 3.0) support"
22 depends on USB && USB_ARCH_HAS_XHCI
24 The eXtensible Host Controller Interface (xHCI) is standard for USB 3.0
25 "SuperSpeed" host controller hardware.
27 To compile this driver as a module, choose M here: the
28 module will be called xhci-hcd.

32 depends on USB_XHCI_HCD
34 config USB_XHCI_HCD_DEBUGGING
35 bool "Debugging for the xHCI host controller"
36 depends on USB_XHCI_HCD
38 Say 'Y' to turn on debugging for the xHCI host controller driver.
39 This will spew debugging output, even in interrupt context.
40 This should only be used for debugging xHCI driver bugs.
45 tristate "EHCI HCD (USB 2.0) support"
46 depends on USB && USB_ARCH_HAS_EHCI
48 The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
49 "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
50 If your USB host controller supports USB 2.0, you will likely want to
51 configure this Host Controller Driver.
53 EHCI controllers are packaged with "companion" host controllers (OHCI
54 or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
55 will connect to EHCI if the device is high speed, otherwise they
56 connect to a companion controller. If you configure EHCI, you should
57 probably configure the OHCI (for NEC and some other vendors) USB Host
58 Controller Driver or UHCI (for Via motherboards) Host Controller
61 You may want to read <file:Documentation/usb/ehci.txt>.
63 To compile this driver as a module, choose M here: the
64 module will be called ehci-hcd.
66 config USB_EHCI_ROOT_HUB_TT
67 bool "Root Hub Transaction Translators"
68 depends on USB_EHCI_HCD || USB_CHIPIDEA_HOST
70 Some EHCI chips have vendor-specific extensions to integrate
71 transaction translators, so that no OHCI or UHCI companion
72 controller is needed. It's safe to say "y" even if your
73 controller doesn't support this feature.
75 This supports the EHCI implementation that's originally
76 from ARC, and has since changed hands a few times.
78 config USB_EHCI_TT_NEWSCHED
79 bool "Improved Transaction Translator scheduling"
80 depends on USB_EHCI_HCD || USB_CHIPIDEA_HOST
83 This changes the periodic scheduling code to fill more of the low
84 and full speed bandwidth available from the Transaction Translator
85 (TT) in USB 2.0 hubs. Without this, only one transfer will be
86 issued in each microframe, significantly reducing the number of
87 periodic low/fullspeed transfers possible.
89 If you have multiple periodic low/fullspeed devices connected to a
90 highspeed USB hub which is connected to a highspeed USB Host
91 Controller, and some of those devices will not work correctly
92 (possibly due to "ENOSPC" or "-28" errors), say Y. Conversely, if
93 you have only one such device and it doesn't work, you could try

339 The Open Host Controller Interface (OHCI) is a standard for accessing
340 USB 1.1 host controller hardware. It does more in hardware than Intel's
341 UHCI specification. If your USB host controller follows the OHCI spec,
342 say Y. On most non-x86 systems, and on x86 hardware that's not using a
343 USB controller from Intel or VIA, this is appropriate. If your host
344 controller doesn't use PCI, this is probably appropriate. For a PCI
345 based system where you're not sure, the "lspci -v" entry will list the
346 right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
