53 The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
54 "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
55 If your USB host controller supports USB 2.0, you will likely want to
Thierry Vignaudb967c882009-02-11 13:31:05 -080056 configure this Host Controller Driver.
Linus Torvalds1da177e2005-04-16 15:20:36 -070057
58 EHCI controllers are packaged with "companion" host controllers (OHCI
59 or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
Jesper Juhlb3c29d82006-01-10 00:35:22 +010060 will connect to EHCI if the device is high speed, otherwise they
Linus Torvalds1da177e2005-04-16 15:20:36 -070061 connect to a companion controller. If you configure EHCI, you should
62 probably configure the OHCI (for NEC and some other vendors) USB Host
63 Controller Driver or UHCI (for Via motherboards) Host Controller
64 Driver too.

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

639 The U132 adapter is a USB to CardBus adapter specifically designed
640 for PC cards that contain an OHCI host controller. Typical PC cards
641 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
642 adapter will *NOT* work with PC cards that do not contain an OHCI
643 controller.
644
Matt LaPlante3cb2fcc2006-11-30 05:22:59 +0100645 For those PC cards that contain multiple OHCI controllers only the
Tony Olechd774efe2006-09-13 11:27:35 +0100646 first one is used.
647
648 The driver consists of two modules, the "ftdi-elan" module is a
649 USB client driver that interfaces to the FTDI chip within ELAN's
650 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
651 controller driver that talks to the OHCI controller within the
652 CardBus cards that are inserted in the U132 adapter.
653
654 This driver has been tested with a CardBus OHCI USB adapter, and
655 worked with a USB PEN Drive inserted into the first USB port of
656 the PCCARD. A rather pointless thing to do, but useful for testing.
