23 ---help---
24 The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
25 "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
26 If your USB host controller supports USB 2.0, you will likely want to
27 configure this Host Controller Driver. 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.

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.

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.

143 The Open Host Controller Interface (OHCI) is a standard for accessing
144 USB 1.1 host controller hardware. It does more in hardware than Intel's
145 UHCI specification. If your USB host controller follows the OHCI spec,
146 say Y. 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.

230 host controller). If your USB host controller conforms to this

232 with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
233 i810, i820) conform to this standard. Also all VIA PCI chipsets
234 (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro

244 help
245 The U132 adapter is a USB to CardBus adapter specifically designed
246 for PC cards that contain an OHCI host controller. 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.
