103 ---help---
104 The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
105 "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
106 If your USB host controller supports USB 2.0, you will likely want to
107 configure this Host Controller Driver.
108
109 EHCI controllers are packaged with "companion" host controllers (OHCI
110 or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
111 will connect to EHCI if the device is high speed, otherwise they
112 connect to a companion controller. If you configure EHCI, you should
113 probably configure the OHCI (for NEC and some other vendors) USB Host
114 Controller Driver or UHCI (for Via motherboards) Host Controller
115 Driver too.
116
117 You may want to read <file:Documentation/usb/ehci.rst>.

635 help
636 The U132 adapter is a USB to CardBus adapter specifically designed
637 for PC cards that contain an OHCI host controller. Typical PC cards
638 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
639 adapter will *NOT* work with PC cards that do not contain an OHCI
640 controller.
641
642 For those PC cards that contain multiple OHCI controllers only the
643 first one is used.
644
645 The driver consists of two modules, the "ftdi-elan" module is a
646 USB client driver that interfaces to the FTDI chip within ELAN's
647 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
648 controller driver that talks to the OHCI controller within the
649 CardBus cards that are inserted in the U132 adapter.
650
651 This driver has been tested with a CardBus OHCI USB adapter, and
652 worked with a USB PEN Drive inserted into the first USB port of
653 the PCCARD. A rather pointless thing to do, but useful for testing.
