135 If your USB host controller supports USB 2.0, you will likely want to
136 configure this Host Controller Driver.
137
138 EHCI controllers are packaged with "companion" host controllers (OHCI
139 or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
140 will connect to EHCI if the device is high speed, otherwise they
141 connect to a companion controller. If you configure EHCI, you should
142 probably configure the OHCI (for NEC and some other vendors) USB Host
143 Controller Driver or UHCI (for Via motherboards) Host Controller
144 Driver too.

654 help
655 The U132 adapter is a USB to CardBus adapter specifically designed
656 for PC cards that contain an OHCI host controller. Typical PC cards
657 are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
658 adapter will *NOT* work with PC cards that do not contain an OHCI
659 controller.
660
661 For those PC cards that contain multiple OHCI controllers only the
662 first one is used.
663
664 The driver consists of two modules, the "ftdi-elan" module is a
665 USB client driver that interfaces to the FTDI chip within ELAN's
666 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
667 controller driver that talks to the OHCI controller within the
668 CardBus cards that are inserted in the U132 adapter.
669
670 This driver has been tested with a CardBus OHCI USB adapter, and
671 worked with a USB PEN Drive inserted into the first USB port of
672 the PCCARD. A rather pointless thing to do, but useful for testing.
