The U132 632 adapter will *NOT* work with PC cards that do not contain an OHCI 633 controller. 634 635 For those PC cards that contain multiple OHCI controllers only the 636 first one is used. 637 638 The driver consists of two modules, the "ftdi-elan" module is a 639 USB client driver that interfaces to the FTDI chip within ELAN's 640 USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host 641 controller driver that talks to the OHCI controller within the 642 CardBus cards that are inserted in the U132 adapter. 643 644 This driver has been tested with a CardBus OHCI USB adapter, and 645 worked with a USB PEN Drive inserted into the first USB port of 646 the PCCARD.
