+          The U132 adapter is a USB to CardBus adapter specifically designed
+          for PC cards that contain an OHCI host controller. Typical PC cards
+          are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
+          adapter will *NOT* work with PC cards that do not contain an OHCI
+          controller.
+
+          For those PC cards that contain multiple OHCI controllers only ther
+          first one is used.
+
+          The driver consists of two modules, the "ftdi-elan" module is a
+          USB client driver that interfaces to the FTDI chip within ELAN's
+          USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
+          controller driver that talks to the OHCI controller within the
+          CardBus cards that are inserted in the U132 adapter.
+
+          This driver has been tested with a CardBus OHCI USB adapter, and
+          worked with a USB PEN Drive inserted into the first USB port of
+          the PCCARD. A rather pointless thing to do, but useful for testing.
+
+          It is safe to say M here.

+* Host Controller Driver for the Elan Digital Systems U132 adapter
+*
+* Copyright(C) 2006 Elan Digital Systems Limited

+*
+* This program is free software;you can redistribute it and/or
+* modify it under the terms of the GNU General Public License as
+* published by the Free Software Foundation, version 2.
+*
+*
+* This driver was written by Tony Olech(tony.olech@elandigitalsystems.com)
+* based on various USB host drivers in the 2.6.15 linux kernel
+* with constant reference to the 3rd Edition of Linux Device Drivers
+* published by O'Reilly
+*
+* The U132 adapter is a USB to CardBus adapter specifically designed
+* for PC cards that contain an OHCI host controller. Typical PC cards
+* are the Orange Mobile 3G Option GlobeTrotter Fusion card.
+*
+* The U132 adapter will *NOT *work with PC cards that do not contain
+* an OHCI controller. A simple way to test whether a PC card has an
+* OHCI controller as an interface is to insert the PC card directly
+* into a laptop(or desktop) with a CardBus slot and if "lspci" shows
+* a new USB controller and "lsusb -v" shows a new OHCI Host Controller
+* then there is a good chance that the U132 adapter will support the
+* PC card.(you also need the specific client driver for the PC card)
+*
+* Please inform the Author and Maintainer about any PC cards that
+* contain OHCI Host Controller and work when directly connected to
+* an embedded CardBus slot but do not work when they are connected
+* via an ELAN U132 adapter.
