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
Jesper Juhlb3c29d82006-01-10 00:35:22 +010014 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.
Linus Torvalds1da177e2005-04-16 15:20:36 -070018
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
Jesper Juhlb3c29d82006-01-10 00:35:22 +010021 will connect to EHCI if the device is high speed, otherwise they
Linus Torvalds1da177e2005-04-16 15:20:36 -070022 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.

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
Dan Streetmanba47f662006-05-24 09:39:16 -070050 This supports the EHCI implementation that's originally

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.

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.

186 controller.

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.
